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

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

Features:

• 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 µs RTC resolution
• Advanced message filtering & transmit functionality
• Start/stop logging triggers based on CAN ID & databytes
• Silent mode, bit rate auto-detection, cyclic logging
• Extractable 8 GB industrial SD card (= months of data)
• Fast boot time. Safely disconnect during use
