Use Cases

The CANedge1 is a powerful, standalone CAN logger for standalone CAN logging, diagnostics and development.

Vehicle 'black box'
Need to monitor data from your vehicle fleet?

The CANedge1 is ideal for recording data over long periods from fleets - incl. cars (via OBD2) and heavy-duty vehicles (via J1939). With filters, compression & cyclic logging you can log months or years of data. This makes the device well-suited as an automotive data logger for e.g. warranty/legal data storage or optimization. Further, by adding GNSS/IMU data, you'll be able to exactly pin-point where an issue occurred - and time-sync it to valuable information about driving behavior and vehicle dynamics.
Fleet Monitoring Offline Data Storage SD Card
Rare issue identification
Need to identify a rare, but critical issue?

If you have e.g. production equipment that periodically exhibts an issue the CANedge1 is a great diagnostics tool. Simply connect it and leave it in, creating a rolling window of e.g. the last X months of data. If the issue occurs, you can extract the raw data, DBC decode it and plot it for quick diagnostics. Further, with the built-in IMU, you can deploy the CANedge1 so as to gain e.g. acceleration or angular rate data from e.g. industrial robotics or machinery to aid in your diagnostics.
Rare issue identification
Equipment development & optimization
Need to optimize your CAN based equipment based on long-term data?

The standalone CANedge1 is ideal for recording data from equipment deployed in the field: It is durable, compact and simple to install. You can e.g. pre-configure the device - and ship it to the end-users for installation. Further, the GNSS/IMU module adds 40+ signals like position, speed, acceleration, distance and more - enhancing your insights. Further, the built-in sensor fusion ensures that these signals gain three times the accuracy vs. GNSS-only receivers.
