CANedge2: 2x CAN Bus Data Logger (SD + WiFi)
The plug & play 2x CAN/LIN logger records timestamped CAN data (Classical/CAN FD) to the extractable 8 GB industrial SD card.
The compact device connects via WiFi access points to securely push data to your own server – with support for over-the-air updates.
Ideal for telematics, R&D field tests, diagnostics and predictive maintenance.
Software/APIs are free & open source – with no subscription fees or vendor lock-in.
