The CAN-BUS Shield V2 still uses MCP2515 as CAN-BUS controller and MCP2551 as CAN transceiver. Despite of that, there are really many updates. First and most importantly, OBD-II or CAN standard pinout can be selected by switching jumpers on DB9 interface, the default pinout is OBD-II. Secondly we add a TF card slot for data storage and the CS pin can be either set to D4 or D5. The INT pin can also be set to D2 or D3 by switching jumpers on the back of the shield. If you want to use more than 2 CAN-BUS Shield, it is needed to cut P1 pad. In V2, we moved the P1 pad from front to the back of the shield to make it easier to cut and solder. All in one, there are more options for customization.
Consider that the D0/D1 pin are usually used for downloading code, we changed the serial Grove connector to pin A0/A1. The I2C grove connector is also changed to more reasonable standard SDA/SCL pin instead of previous A4/A5. The two grove connectors are both changed to horizontal rather than vertical to the shield so that it would be more convenient when connecting to other grove modules.
