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?

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.

Vehicle to Cloud Underground Mining Data Maintenance

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.

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 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.
