The CANedge2 is a powerful, standalone CAN logger for ad hoc analysis, diagnostics and development.

However, the device truly shines in e.g. fleet telematics and IoT machinery setups:

Vehicle to Cloud Underground Mining Data Maintenance

Underground mining & construction

Want to implement vehicle telematics - but your vehicles are underground?

Maintaining & optimizing heavy-duty mining vehicles using data is vital. However, vehicles often only re-surface briefly - rendering cellular telematics dongles useless. With the CANedge2, you can log data to the SD and upload it when vehicles re-surface and get in range of WiFi. Learn more in our mining telematics intro.



Warehouse fleet management

Need to monitor a fleet of AGVs/forklifts in a warehouse?

For site managers/OEMs, the device can collect data from AGV/forklift fleets - e.g. for optimizing battery management. The device has strong WiFi range, can upload via multiple WiFi access points - and can store data on e.g. a local server if preferred.

IoT Vehicle Cloud Warehouse Forklift Data Electric EV Battery


Wireless IoT CAN logger Vehicle Telematics OBD2 J1939 WiFi

Vehicle telematics

Need to monitor & optimize a vehicle fleet in near real-time?

For wireless 'on-road' upload of data, the device can connect via a 3G/4G hotspot - optionally powered via a DB9-USB adapter. Alternatively, the device can upload data when the vehicle periodically returns to e.g. a garage WiFi. Ideal for e.g. OBD2 logging, truck fleet management, predictive maintenance and more.



Remote machine monitoring

Need to remotely monitor & troubleshoot industrial machinery?

Production machinery OEMs often need to deal with diagnostics, maintenance and field breakdowns. Local troubleshooting can be costly and slow. Here, the CANedge2 can be installed to diagnose issues remotely - and/or set up wireless predictive maintenance. Further, with configuration over-the-air, you can e.g. reset the machine via remote controlled transmit messages. Learn more in our CANopen data logger intro.

Predictive Maintenance Machine Data CAN bus


White Label Vehicle Data Logger Hardware Platform Cloud Analytics

White label partnerships (OEMs/integrators)

Need a data logger in your product - or as a telematics platform?

The CANedge2 CAN bus logger is easy to integrate in existing systems, making it ideal as a hardware platform for CAN bus telematics solutions. Configuration files, server interfaces, log files etc. all utilize open file formats, with open source API tools available. Further, all software is 100% open source and customizable - for example the CANcloud telematics platform, or the customizable Grafana dashboards.





The CANedge2 CAN data logger is our "next generation" WiFi CAN logger.

We've taken all learnings & feedback from the CLX000 series - in particular the CL3000 - and applied it in the CANedge2.

Key improvements with the CANedge2 include:

WiFi

  • WiFi: Vastly improved WiFi (stability, range, dynamic switching between 1-5 WiFi access points, device status updates)
  • Over-the-air updates: Update device configuration/firmware over-the-air (OTA) with a few clicks - incl. via batch tools
  • Security: Secure HTTPS transfers (instead of unsecured FTP). Encrypted credentials on SD
  • Clouds: S3 interface enables plug & play integration in e.g. AWS, Google Cloud, Azure - and free S3 servers like MinIO
  • S3 API: The S3 API enables easy automation of your server file management incl. e.g. OTA updates and log file processing

Mechanical

  • Aluminum enclosure: New enclosure is far more robust and enables use of different external WiFi antennas
  • Power out: Power external modules via the 2nd port e.g. a GPS-to-CAN, Temperature-to-CAN or 3G/4G hotspot
  • Channels: 2xCAN channels, which enables logging from 2 CAN buses in parallel
  • Industrial SD: The CANedge uses an industrial SD card, improving performance, life time, temperature range & more
  • Extractable SD: The SD can be extracted to transfer data at 80 MB/s (vs 0.5 MB/s for the CLX000 via USB)

Log files & software/API

  • MDF4 log files: Popular binary MDF4 format - more compact than CSV, faster to process, supported by many CAN tools
  • CANcloud: Open source CANcloud browser tool makes it easy to manage log files and e.g. configure devices (incl. OTA)
  • JSON Schema: Config files are based on the JSON Schema concept, supported by many open source tools
  • asammdf GUI: Enables user-friendly MDF4 log file editing, DBC-conversion (incl. OBD2/J1939), graphical plots & more
  • asammdf API: Easily process your data at scale and automate the creation of e.g. reports/databases/dashboards
  • Converters: Open source light-weight converters enable drag & drop/CLI conversion of MDF4 into e.g. *.csv and *.asc

Data logging

  • Lossless: The CANedge can log extreme bus loads with zero message loss (the CLX000 is limited to ~1000 frames/sec )
  • Compression: Optional compression lets you reduce file size by 50-80% vs. the CLX000
  • Encryption: Optional encryption lets you encrypt log files on the SD card for added security
  • Advanced configuration: More advanced filters & transmit lists (e.g. up to 128 filters vs. 8 on CLX000)
  • Precision: 20x higher RTC resolution (50 micro seconds) - with advanced WiFi RTC sync
  • Boot time: Much faster boot time vs the CLX000 (~1 sec vs. ~10 sec)
  • CAN FD: The CANedge2 supports CAN FD (Flexible Data-Rate), making it future proof

Further, the CANedge series will be our focus for new firmware upgrades - meaning you'll see a lot of powerful features added in addition to the above over the coming period.


The CANedge1 and CANedge2 are 100% identical, except for the WiFi functionality in the CANedge2.

If you only need to collect your CAN data rarely and the device is physically accessible with ease, then the CANedge1 is typically enough. However, if you need to collect your data frequently and ideally remotely, the CANedge2 will quickly be worthwhile. In particular, if you need to collect data across a fleet of vehicles or machines, the CANedge2 is far more practical and cost effective.

The CANedge2 also has the added advantage that you can fully automate your data collection, as well as your data processing workflow. For example, you can set up automated Python API scripts to modify your data, DBC decode it - and e.g. setup telematics dashboards. The CANedge2 is also easier to manage in the field as you can monitor the status via the CANcloud telematics platform and e.g. perform over-the-air configuration and firmware updates.


The size of a raw MF4 log files depends on the type of application. However, on average a raw CAN bus log file will be ~50-100 MB/hour if no configuration changes are made.

With an 8 GB SD card, the CANedge would thus be able to record about ~80-160 hours of non-stop data.

However, the CANedge is designed to optimize this drastically via below configuration options:

  • Compression: Enabling compression will reduce the data size by 50-80%
  • Filters: You can specify which CAN IDs to accept or reject (incl. via ranges and masks)
  • Prescalers: You can selectively prescale filtered CAN IDs by count, period or data. This e.g. lets you record only every 5th observation, or one observation per 500 ms. The data prescaler lets you record observations only if data byte X or Y changes
  • Control signal: This lets you specify when to start/stop logging based on CAN ID and data byte patterns

By using these options, most users end up with ~4-15 MB/hour. On an 8 GB SD card, this results in 500-2000 hours of non-stop data (1-3 months). On a 32 GB SD card, this corresponds to 2000-8000 hours of non-stop data (4-12 months).

Should the SD card become full, enabling cyclic logging will allow the CANedge CAN data logger to keep recording data by deleting the oldest log files first.


The CANedge series is generally superior when it comes to logging data to the SD card vs. the CLX000. However, the CANedge does not support real-time streaming via USB. For this type of use case, we would recommend e.g. the CL2000. In the medium-term we may potentially add wireless real-time streaming for the CANedge2 - streaming your CAN bus data via WiFi.


In the below, we outline the basics of how you get started logging raw CAN data.

  • Connect the CAN logger to your CAN bus (optionally using one of our DB9 adapter cables)
  • The device powers on, detects the bit rate and starts logging raw data to the SD card
  • Disconnect the device, extract the mini SD and insert it into your PC (optionally via an SD adapter)
  • From here, you can open the raw log files in e.g. the asammdf GUI/API for export/DBC conversion

Once you've verified that you're logging data as expected, you can set up the WiFi/server for wireless CAN bus data upload:

  • Set up your S3 server (see the getting started guide) - for simple setups, this can be done in <5 mins
  • Open the device configuration file via a text editor - or, preferably, via the CANcloud editor
  • In the configuration, enter your WiFi hotspot SSID/password and server details
  • Download the updated configuration file to your device SD card and power on the device
  • The device now auto-pushes both logged data and it's configuration file to your server
  • You can now optionally manage your devices/data from the browser by logging into your server via CANcloud

From here, you can do more advanced things - for example:

  • You can encrypt your WiFi/server credentials using the CANcloud editor tools
  • You can enable TLS on your server/device to transfer data securely via HTTPS
  • You can use over-the-air updates to change the configuration/firmware of your device(s)
  • You can set up automated processing of your data via the S3/MDF4 APIs
  • You can download the CANcloud source code, optionally customize it and host your own version

For more details on how the device works, we recommend reviewing the getting started guide and product manual.


The CANedge2 combines two areas: High performance CAN data logging - and a unique approach to CAN bus telematics.

First, it serves as an extremely powerful CAN bus data logger with specs that match some of the best pro CAN loggers on the market (at less than 50% of the cost).

Second, it provides a fresh angle on today's CAN bus telematics industry by giving back control to the users:

  • You send your CAN data to your server via your WiFi access points
  • We charge no subscription fees - and we never see your data
  • Modern end-to-end IoT security is a corner-stone in the design - where many existing solutions suffer from legacy issues

While you may get fewer bells & whistles than with a full-blown telematics solution, many use cases actually benefit from this as you tailor your solution to your needs. And with our free CANcloud software you have an excellent starting point.

Finally, we're developers - and we've designed the CANedge2 to be awesome to work with:

  • We log in an industry standard log file format (MDF4) which is non-proprietary, easy to work with and supported by many software/API tools - incl. the 100% open source asammdf GUI/API
  • Files are uploaded using the popular S3 object storage concept. This lets you manage files via the open source S3 REST API available in all major programming languages - on both your private/cloud servers
  • Our configuration file is based on the popular open source JSON Schema concept - supported by many open source tools & APIs (e.g. the react-jsonschema-form used in CANcloud)
  • The CANcloud data & device management tool is 100% open source and can be easily customized for your needs
  • The free telematics dashboard integration with Grafana lets you set up 100% custom dashboards in minutes

Yes, you can use our step-by-step guide to setting up 100% free, customizable telematics dashboards for visualizing your CAN bus data in your browser. The integration uses our free Python API to DBC decode raw CAN data (from local disk or your S3 server) and push it to a time series database. From here, the data can be visualized via the popular dashboard tool, Grafana, enabling fully custom dashboards - e.g. for J1939 telematics, OBD2 telematics, marine telematics, automotive predictive maintenance and other use cases.


Yes - and it's really easy! You just need to host an S3 compatible server e.g. on your own PC.

We recommend MinIO Server, which is a 100% free, open source & lightweight solution. You simply download it, run a command and you're ready to setup your WiFi CAN bus data transfer.

For details on how to get started with your own S3 server, see our documentation.


Yes, the CANedge2 WiFi CAN logger is designed for easy CAN-to-cloud integration.

For AWS, Google Cloud, Wasabi S3 and DigitalOcean it's very simple as they natively support the S3 interface - letting you get started with the WiFi CAN bus data transfer in minutes.

For Azure and other cloud servers, you simply need to run an S3 gateway (e.g. MinIO Server) on the server. This takes a few minutes extra vs. e.g. AWS/Google Cloud - but is still very simple to set up.

For more details, see our documentation: Setting up an S3 server.


Yes. There are two aspects of the CANedge2 that makes this very simple to set up:

First, the CANedge2 uses the automotive industry standard format, MDF4 (aka *.MF4). This means that most CAN software tools can process the log files - and multiple open source MDF4 APIs exist, making the processing simple.

Second, you'll typically want to set up a script that manages the files directly on your server. Here, the CANedge2 utilizes the S3 interface to upload files, which means you can use any S3 API/SDK to manage the uploaded files. For example, the open source AWS SDK can be used for this purpose.

See also our github page for useful script examples.


The CANedge2 CAN data logger offers a lot of powerful functionality for optimizing cloud server storage and cellular data transfer costs:

  • Filters: You can add up to 128 filters to get specifically the data you want
  • Prescalers: You can e.g. specify that CAN ID X should be logged only every Y ms
  • Compression: The CAN logger supports embedded data compression, reducing log file size by 50-70%
  • 5 hotspots: Add e.g. a garage WLAN as #1 and a 4G in-vehicle hotspot as #2 to dynamically optimize cellular usage
  • Over-the-air: You can change all configurations remotely - e.g. adjusting filters on-the go or enabling/disabling logging

The CANedge2 does not have built-in GPS, but it's easy to add due to the modular design.

Specifically, the 2nd port can be configured to supply 5V power to 1-3 external modules.

As such, you can power your CANedge2 via the CAN bus via the 1st port - and add the CANmod.gps GPS-to-CAN module in the 2nd port. The data from the GPS module will then be recorded on the CANedge2 SD card (i.e. it's not sent into the CAN bus, retaining silent mode). You can naturally set this up while at the same time logging other CAN data via Channel 2 at the same time.


Yes. The CANedge2 WiFi CAN data logger can connect to any WiFi hotspot: WLAN, 3G, 4G, 5G.

For example, you can connect the CANedge2 to a USB cellular WiFi router. This USB hotspot can be powered via the 2nd port of the CANedge, allowing for a simple installation in e.g. vehicles (as you'll just power the CANedge2 via the CAN bus connector).

We do not include a built-in SIM card in the CANedge2 because we believe the WiFi approach is superior:

  • A built-in SIM card adds substantial costs, but is not always needed (e.g. in production sites, warehouses, mines, ...)
  • With an external cellular hotspot (powered via the 2nd port), the CANedge2 can easily gain cellular connectivity
  • By supporting 5 hotspots, the CANedge2 can dynamically switch from e.g. a 4G hotspot to a WLAN to minimize data costs
  • You can e.g. add up to 5 driver smartphone hotspots to the CANedge2 (log file META tags shows the SSID, aka driver)
  • The external antenna (and e.g. 4G hotspot) are extendable and can e.g. be moved outside shielding for better range
  • The CANedge2 can easily connect to a 5G hotspot - i.e. you won't have to worry about future compatibility

No, the CANedge2 has an 8 GB SD card and can work as a stand-alone CAN logger without WiFi. For most CAN bus applications, 8 GB will provide many weeks - if not many months - of data capacity (in particular when using the binary MDF4 format). Further, with cyclical logging, you can ensure you always keep the most recent data - should you encounter extreme scenarios where you run out of space.

When connectivity returns, the CANedge2 will automatically start pushing the data to your server.

Note: Once a file is transferred, it's deleted from the SD card - but only if the transfer is successful.


The CANedge2 can split files every 10-86400 seconds or every 1-512 MB. When a new log file is created, it's automatically transferred to your server if the CANedge2 is connected to a WiFi hotspot. As such, you can get a steady stream of incoming files and by using the APIs for MDF4 log files and the S3 interface, you can easily auto-process the incoming data in near real-time.

For most intents and purposes, however, we recommend to use medium/larger log file sizes (e.g. 5-20 MB) to avoid an excessive amount of log files in your server.

We also plan to introduce socketCAN streaming as a future feature, which will allow you to stream CAN data via WiFi for real-time analysis.


MQTT (Message Queuing Telemetry Transport) is a light weight messaging protocol, which is used by many IoT devices. As such, it is also supported by some cloud server IoT services for enabling e.g. statistics and analytics.

We originally considered the MQTT protocol as an option for uploading data via the CANedge2, but found that it is less suited for "big data" uploading. The protocol is ideal for very small packets at low resolution sent by e.g. streaming devices (with no local storage capability). However, for logging the full CAN bus load from e.g. a vehicle, the MQTT protocol would quickly get overloaded - resulting in very poor performance. For example, the protocol would make it practically impossible to "offload" all the data recorded on the CANedge2 SD card after e.g. a period with no coverage as new data would be recorded at a higher rate than it could be uploaded.

Instead, the CANedge2 utilizes the S3 REST interface with the HTTP(S) protocol. This combination is ideal for uploading large log file packets to either local/dedicated servers like MinIO or cloud servers like e.g. AWS, Google Cloud and Azure. In particular, it allows for uploading data from the CANedge2 much faster rate than new data is recorded - meaning that the device can stay offline for longer periods and still offload all log files when it regains coverage.


At this stage, we've not included an Access Point mode to the CANedge2 (contrary to the CL3000). However, we may add this at a later stage if it's useful to our users.


We offer a 32 GB upgrade (it's an option when you buy from our site), using tested industrial SD cards. You can also add your own SD card (up to 32 GB), though we recommend in this case to test the device to confirm expected functionality.


Yes, we actively seek to collaborate with partners - in particular cloud analytics providers.

The CANedge2 is designed to be easy to work with (plug & play cloud integration, open source file format, S3 interface, APIs, ...). The aim is that the device can serve as a plug & play solution for analytics providers that wish to focus on developing other aspects than hardware.

As a team, we're very open to suggestions from partners - assuming features/changes improve the overall product.

We're flexible in terms of models and recommend that you reach out to us to discuss further.
