Products & Technology Shields
#1

Hi ,

I just bought CAN-BUS shield v1.2 from seeeduino, and followed instruction per seeedstudio.com/wiki/CAN-BUS_Shield,
I got “can bus shield init fail”

then I just connect one assy(CAN-BUS shield v1.2 stacked on Uno R3) to computer via USB, I still got “can bus shield init fail”

1.can you share the circuit schematic drawing of CAN-BUS shield v1.2, the one on wiki is v0.9b
2.any idea why “init fail”

THanks in advance!

Problem solved.

I think document should be upgraded and aligned to each other!

New guys will thank you for that ! :mrgreen:
