Hi,
I bought CAN-BUS Shield V2.0 but i can’t find manual for this shield. On the website seeedstudio.com i found manual only for V1.2, unless I’m wrong.
I dont now how to connect configuration pads on the back shield. See the photo.
Currently, the CAN Shield does not send a signal on CAN H and CAN L.
Thank you in advance for your help

Hi @jaro850
The default pads are connected to A on the board.
For Arduino UNO, it works well by default setting.
It should be some operation error led the CAN shield can’t send the signal on CAN H and CAN L.
Is the SD card used at the same time? If the SD card is used at the same time, it may cause CAN fail to work.
If want to connect it to B, you can use a resistor or tin directly to connect SPI pads to B and cut off the connection between SPI pads and A at the same time.
