CANedge2 (8 GB) – 2x CAN BUS Data Logger with WiFi


The plug & play 2xCAN/LIN logger records timestamped CAN data (Classical/CAN FD) to the extractable 8 GB industrial SD card. The small device connects via WiFi access points (e.g. WLAN or 3G/4G routers) to securely push data to your server. Further, global fleets can easily be managed via over-the-air firmware & config updates.



The plug and play 2xCAN/LIN logger records timestamped CAN data (Classical/CAN FD) to the extractable 8 GB industrial SD card (optionally 32 GB).

The small device connects via WiFi access points (e.g. WLAN or 3G/4G routers) to securely push data to your server. Further, global fleets can easily be managed via over-the-air firmware & config updates.

The CANedge2 is ideal for telematics & vehicle fleet management – as well as R&D field testing, diagnostics and predictive maintenance of machinery.

Software/APIs are free & open source – with no subscription fees or vendor lock-in.

Reinventing telematics

Today, fleet telematics is vital across vehicles and machines. However, end users face challenges: Expensive subscriptions. No data ownership. Security concerns. Lack of control.

The CANedge2 provides a modern alternative:

  • Simply add your WiFi access point & server details to start.
  • Log data to the SD – auto-upload when connected to WiFi.
  • Configure file split size/period to control upload frequency.
  • 100% secure: HTTPS, credential encryption and more.
  • Over-the-air updates (firmware & configuration).
  • 2nd port can power external modules (e.g. 4G hotspot, GPS).
  • Easily use with local, dedicated & cloud servers.
  • Supports multiple hotspots (e.g. optimize WLAN vs. cellular).
  • No fees. Open source software. Ideal for white label


  • Dual high speed CAN/LIN (incl. CAN FD) channels
  • Binary MDF4 log file format (extensive software support)
  • Lossless logging at full bus load – with 50 ?s RTC resolution
  • Advanced message filtering & transmit functionality
  • Start/stop logging triggers based on CAN ID & databytes

  • Real-Time Clock: Yes – CAN frames are date & timestamped with 50 microsecond resolution. The RTC can be configured to match local time zones (default: UTC)
  • Log File Format: Log data in industry standard binary MDF4 (easily convert to e.g. CSV, ASC, pandas, MATLAB, …)
  • Silent Mode: Configurable silent mode: Restricted (acknowledge only) or monitoring (zero transmission)
  • Filters: 128/64 regular/extended ID filters per channel (range, mask, acceptance, rejection, pre-scaling)
  • Transmit: Transmit lists of CAN frames per channel (single-shot/periodic) – e.g. for OBD2 requests
  • Cyclic Logging: Optional cyclic logging mode (oldest log file is deleted when SD card is full)
  • Advanced Triggers: Control signal lets you start/stop logging based on custom CAN IDs & data thresholds
  • CAN Heartbeat: Optionally transmit heartbeat CAN frame with device status, storage used & RTC time
  • File Split: Configurable log file split size (by size: 1-512 MB and/or by time period: 0-86400s)
  • Power Safe: 100% power safe data logging – no file corruption when disconnected
  • Unique Device ID: Each device has a globally unique ID ensuring unique log file naming
  • Data Encryption: Log files can be encrypted at rest on the SD card for security/GDPR/CCPA purposes [pending FW]
