KOOBOOK MCP2515 CAN Bus Shield Controller Expansion Board Development Board SPI Interface Communication Speed High for Arduino blue KB304

This is a LseeStudio CAN-BUS Shield V1.1. The description should really mention that not that any documentation exists.CS is connected to pin 10 and the SPI output is connected to the ICSP header for some reason. No library or other shield uses this configuration so finding software for this board is difficult without modifying existing libraries. The only part they have correct to the common standard is the INT on D2. And to make it worse there's no solderable jumpers to reconfigure any of it (especially important for CS). The IC on mine is also soldered on crooked, but luckily no pads were shorted.I ultimately ended up soldering bodge wires to the more standard pinout using D10, D11, and D12. I also replaced the 47k SMD resistor next to the MCP2551 with a 10k resistor to support higher speeds.I took a gamble buying this one since it was cheaper than the others, and regret my decision. The rework required takes away all the convenience of having it as a shield. Save yourself the headache and buy a different one with an easy to change pinout.

Worked as advertised first try

I got a LseeStudio v1.2 unit. I used the Sparkfun library from Sparkfun's CAN Bus shield hookup guide. With that library there was no need to change the CS pin assignment from Port B,2 (D10) and the SPI was fine. My only complaint is the CAN DB-9 connector touches the USB shell on a Arduino Uno R3. I put a piece of electrical tape between them.

This board is an older version and is not compatible with the Arduino Libraries and the DB9 is a non-standard pin-out.
