CSS CANedge2 device includes an extractable 8-32 GB industrial SD Card (Class 10). This ensures e.g. optimal endurance and rapid offline data transfer (W/R 50/80 MB/s) 
CSS CANedge enables logging of raw CAN/LIN data incl. CAN FD, J1939, CANopen, OBD2, UDS, ISOBUS, NMEA2000 - across any CAN/LIN application. 
CSS CANedge2 is designed to be extremely compact (75 x 47 x 20 mm). Despite the robust aluminium enclosure, it weighs only 100G. 
2nd port (CH2) provides a configurable 5V power out, letting you easily power e.g. CANmod sensor-to-CAN modules (temperature, analog/digital/pulse, …) 
CSS CANmod.router module can e.g. be used as a plug & play add-on for the CANedge (powered via 2nd port) - letting you log 1 x CAN (via CH1) + 4 x CAN (via CH2) 
2x high speed CAN channels enable time-synced recording of data from two CAN buses - ideal for e.g. many heavy duty vehicle applications 
CSS CANedge2 comes with flanges to enable easy installation at scale. The 'mounting kit' includes screws and optional vibration dampeners.
Reinventing telematics
Today, fleet telematics is vital across vehicles and machines.
However, end users face challenges: Expensive subscriptions. No data ownership. Security concerns. Vendor lock-in.
CSS CANedge2 provides a modern alternative:
- Upload data to your own local/dedicated/cloud server
- Simply add WiFi access point & server details to the config
- Log data to the SD and auto-upload when connected to WiFi
- Configure file split size/period to control upload frequency
- 100% secure: HTTPS, credential encryption and more
- Manage via over-the-air updates (firmware & configuration)
- Power e.g. sensor-to-CAN modules via the 2nd port
- Zero fees. Zero lock-in. Interoperable. Open source tools

- Full GNSS support (GPS, Galileo, BeiDou, GLONASS)
- Built-in gyroscope (roll, pitch, yaw) and accelerometer (X, Y, Z)
- High precision via sensor fusion - even in GNSS hostile areas
- Signals encoded as 'internal' CAN frames (separate channel)
- Configurable message inclusion/frequency (up to 5 Hz)
- DBC file included for easy decoding to human-readable form

Position + Sensor Fusion
Add time-synced GPS positioning to your CAN/LIN data - with sensor fusion (UDR) for 3x higher accuracy.
Speed
Speed data is useful in e.g. fleet telematics to identify speeding, idle time, asset utilization rates and more.
Altitude
Altitude is key in e.g. analysis of fuel/battery consumption - or e.g. in aerospace applications like drones, planes etc.
Attitude
GNSS/IMU enables attitude data, giving a 3D view of the asset orientation at any time [automotives].
Trip Distance
Odometer data enables easy tracking of the trip distance travelled by the asset (since last module power cycle).
Angular Rates
3D IMU angular rates can be used in e.g. the analysis of driving and vehicle dynamics (tire/suspension, drifting, …).
Acceleration Rates
3DIMU acceleration rates can be used in e.g. analysis of driving quality and predictive maintenance.
Geofences
Configurable circular geofences are useful for e.g. theft prevention, safety, automation and more
Timestamp
High precision epoch timestamp is useful e.g. in syncing the CANedge real-time clock.
