The device can be used to log data from any CAN-bus based application: vehicle, automation, robotics, etc. The log is stored in comma separated text file (CSV) and each log entry (CAN-message) has a time stamp. It also has playback function, i.e. can play recorded file back onto a CAN bus, turning the device into a CAN bus simulator. The logger is an ideal solution for applications where small, cheap and simple device is needed to record CAN-bus activity without any additional hardware. Designed and professionally assembled in USA!

Features:

• The device has only one start/stop button, and all the settings are stored in configuration text file on SD card. No external PC or smartphone is required for logger operation.

• Optional message filtering based on ID mask matching.
• Selectable listen-only mode (without CAN bus acknowledge).
• Three LEDs for indication of logger status.
• Open source and open hardware project.

• An example of configuration file: 500 kbps, no acknowledgment of messages, all messages are time stamped and recorded.
• The Use Case: recording OBD-II vehicle bus in parallel with PCAN professional data logger, no differences were found between logs, here is raw and post-processed data

NOTE: Does not come with a SD card, you should buy memory card separately
