Description

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

It's easy-to-use: Simply connect the device to your CAN bus to start logging raw CAN data. Next, extract the data and process it using 100% free open source software/API tools - incl. file format conversion, DBC decoding and plot visualization.

The device includes GNSS/IMU, adding data like position, speed, attitude, acceleration and more.

Ideal for recording CAN/LIN data over weeks, months or years - e.g. for diagnostics, OEM development or legal/warranty purposes.

The device includes an extractable 8-32 GB industrial SD card (Class 10). This ensures e.g. optimal endurance and rapid data transfer (W/R 50/80 MB/s)

The CANedge enables logging of raw CAN/LIN data incl. CAN FD, J1939, CANopen, OBD2, UDS, ISOBUS, NMEA2000 - across any CAN/LIN application.

The device is designed to be extremely compact (75 x 47 x 20 mm). Despite the robust aluminium enclosure, it weighs only 100G.

The 2x high speed CAN channels enable time-synced recording of data from two CAN buses - ideal for e.g. many heavy duty vehicle applications

The 2nd port (CH2) provides a configurable 5V power out, letting you easily power e.g. CANmod sensor-to-CAN modules (temperature, analog/digital/pulse, ...)

The 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)

The CANedge1 comes with flanges to enable easy installation at scale. The 'mounting kit' includes screws and optional vibration dampeners.

GPS & 3D IMU

The CANedge1 comes with cutting-edge GNSS/IMU functionality - perfect for automotive/maritime use cases.

• Add 40+ GNSS/IMU signals to your 2 x CAN/LIN data
• 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
• Optionally sync the CANedge RTC via precise GNSS time
• Flexible deployment via external GNSS antenna

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.

The 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

3D IMU 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

The high precision epoch timestamp is useful e.g. in syncing the CANedge real-time clock.

Use Cases

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

Note: If you need to remotely collect data via WiFi or 4G LTE check out the CANedge2 or CANedge3.

Vehicle blackbox / Event Data Recorder (EDR)

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, data encryption and cyclic logging you can safely log the latest 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. This also makes the CANedge1 an excellent Event Data Recorder (EDR) for e.g. UN R160 or UN R169 requirements.

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.
 

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.
