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.

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.
Bitrates up to 1 Mbps (any non-standard baud rate supported), supports CAN 2.0A (11-Bit ID) and CAN 2.0B (29-Bit ID).
Optional message filtering based on ID mask matching.
Selectable listen-only mode (without CAN bus acknowledge).
Three LEDs for indication of logger status.
Playback function with time accuracy of 3 ms.

Specification:

Support for up to 32GB micro-SD cards (FAT32), for best results the UHS Speed Class 1 (U1) SD card recommended.
Power supply voltage: from +5.5V to +18V DC.
Dimensions: 48.26 x 20.85 mm (1.9 x 0.82 in).
Microcontroller: STM32F405RGT6 (Cortex M4 core).

New useful functions implemented in firmware in August 2018:

Configurable option to start logging on power on.
Option to delete the oldest files if there is less than 10% of free space on the SD card.
File names are now represented by numbers from 0.csv to 99999999.csv and firmware will increment file name number every time you start logging.
Configurable start logging by receiving a marker in a CAN message.
Configurable stop logging by receiving a marker in a CAN message.

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 a memory card separately.

This card as an example is tested with highest CAN throughput.

Excellent CAN Logger

Easy set-up, and I had the device logging CANbus data with a few minutes. If you need a basic CAN logger, this is the device to get!

Small tool, great impact.

Works as advertised.
Check out the documentation .pdf
Create a config.txt file and off you go.
Don't forget to add "start_on_power 1" in there.

A very handy tool, that can be used in situations where there is little space.

Great value, very satisfied.

I found it to be easy to use and setup. The documentation was easy to follow. The settings give it great versatility.
The size of the board and no parts on the backside makes it convenient for mounting with double sided tape.
My only suggestion for improvement is to make the CAN termination resistor on/off software controlled by the SD card.

Nice item, express shipping.

Really tiny board. Good to be embedded in some control unit.
Board is hand assembled but looks good.

Looked promising...

The reality is, if you're not an software engineer (which I'm not) chances are the data will not be usable "as is" !
The explanations for the ID filter are gibberish to me.
The news functions from the last firmware could have improved slightly my experience, but sadly I bought mine in 2017 and I have no idea how to update the firmware (if that is even possible).

It would be so much better if we could set filters to get post-processed data instead of just the raw values.
That would make it match the description of "simple logger" to me. Right now it more a "basic logger".

Neat CAN logger

Very tiny logger, great for awkward spaces. Works just fine at 500kbit/s. Message filtering function is very useful.

Justin | April 5, 2017

Works!

Nicely built CAN logger with excellent support. Make sure your SD card has a msdos (standard) partition table, not GPT. No problems logging at 500kbit/s @ ~35% (canbusload can0@500000) to a Class 10 SD card.
