CAN-Bus Shield V2 Compatible with Arduino for Controller and Transceiver, Arduino Shield Adopts MCP2515 and MCP2551.

Worked perfectly! Was able to use this shield to open and close my homemade truck bed cover using my OEM key fob by intercepting CAN messages.

works good with the Arduino giga and mega, and good documentation

Bien

Works fine so far. Been using it with the canhacker program paired with my uno.

Works great. The SD card holder has a door that swings open. They should probably document this somewhere because its not immediately obvious.

I'm pretty inexperienced with Arduino and CAN, but I had this up and running and pulling data from a GMLAN bus (OBD2-CAN) within an hour. I had no luck with the Seeed libraries, the code is beyond my understanding and the examples don't compile. I got it working with the sandeepmistry OBD2 library after changing CS pin from 9 to 10 by cutting/soldering the pads on the bottom of the board. Loaded the example code and Bam! it's receiving ECU/engine data. Minus one star because the DB9 connector shorts out on the standard UNO USB connector. Clearly was designed for Seeeduino's own board.

So far I've been incredibly disappointed in the documentation and support for this product. The board itself seems well constructed, but I have yet to get it working. The jumper pads on the back of the board do not look like the pads on their documentation. On the site it shows that the jumpers only need to be soldered if you want to change the default configuration, but my board had no jumpers connected out of the box. I'm assuming this means I have to solder all the jumpers before I can get it working. As is this board is useless.

I purchased this to build a CAN-driven tachometer. I used it with an Adruino Uno, a DB9 to OBDII cable, and a 4-digit 7-segment display (Tm1637 driver). I was able to get the project done quickly with the available open-sourced libraries.
