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:

Underground mining & construction

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

Mining fleets often require automated monitoring, performance monitoring and diagnostics. However, vehicles often only re-surface briefly from mines - making it vital to have an offline 'buffer' if no underground WiFi network is available. Here, the CANedge2 logs data to the SD card and auto-uploads it when the vehicles re-surface and come within range of the WiFi. Further, the GNSS/IMU functionality enables easy tracking of assets - and provides vital signals like position, trip distance, speed and accelerations. Learn more in our mining telematics intro.

Underground mining & construction

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. By connecting to the warheouse WiFi, the devices can continuously upload data to your own local/cloud server. This also enables practical predictive maintenace as showcased in this case study of 250+ AGVs.

Warehouse fleet management

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 - or you can use a CANedge3 with internal SIM card for 3G/4G transfer. Alternatively, the CANedge2 can upload data when the vehicle periodically returns to e.g. a terminal WiFi. Ideal for e.g. OBD2 logging, truck fleet management, predictive maintenance and more.

Tip: For 3G/4G use cases, we strongly recommend using the CANedge3.

Vehicle telematics

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.

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.

Reinventing telematics

Today, fleet telematics is vital across vehicles and machines.

However, end users face challenges: Expensive subscriptions. No data ownership. Security concerns. Vendor lock-in.

The CANedge2 provides a modern alternative:

  • Upload data to your own local/dedicated/cloud server
  • Simply add WiFi access point & server details to the config
  • Log data to the SD and auto-upload when connected to WiFi
  • Configure file split size/period to control upload frequency
  • 100% secure: HTTPS, credential encryption and more
  • Manage via over-the-air updates (firmware & configuration)
  • Power e.g. sensor-to-CAN modules via the 2nd port
  • Zero fees. Zero lock-in. Interoperable. Open source tools

GPS & 3D IMU - enrich your data

The CANedge2 comes with cutting-edge GNSS/IMU functionality - perfect for use cases like vehicle telematics.

  • Add 40+ GNSS/IMU signals to your 2 x CAN/LIN data
  • Full GNSS support (GPS, Galileo, BeiDou, GLONASS)
  • Built-in gyroscope (roll, pitch, yaw) and accelerometer (X, Y, Z)
  • High precision via sensor fusion - even in GNSS hostile areas
  • Signals encoded as 'internal' CAN frames (separate channel)
  • Configurable message inclusion/frequency (up to 5 Hz)
  • DBC file included for easy decoding to human-readable form
  • Optionally sync the CANedge RTC via precise GNSS time
  • Flexible deployment via external GNSS antenna

Position + sensor fusion

Add time-synced GPS positioning to your CAN/LIN data - with sensor fusion (UDR) for 3x higher accuracy.


Speed data is useful in e.g. fleet telematics to identify speeding, idle time, asset utilization rates and more.


Altitude is key in e.g. analysis of fuel/battery consumption - or e.g. in aerospace applications like drones, planes etc.


The GNSS/IMU enables attitude data, giving a 3D view of the asset orientation at any time [automotives].

Trip distance

Trip odometer data enables easy tracking of the trip distance travelled by the asset (since last module power cycle).

Angular rates [pending FW update]

3D IMU angular rates can be used in e.g. the analysis of driving and vehicle dynamics (tire/suspension, drifting, ...)

Acceleration rates

3D IMU acceleration rates can be used in e.g. analysis of driving quality and predictive maintenance.


Configurable circular geofences are useful for e.g. theft prevention, safety, automation and more


The high precision epoch timestamp is useful e.g. in syncing the CANedge real-time clock.
