How to connect EVQ7225-QJ-01A to VBpro 4

Hi, how do I connect the EVQ7225-QJ-01A to the I2C bus?

Do the TX/RX pins on the board correspond to I2C SCL/SDA?

Hi @alex05020907,

The MPQ7225 uses a CAN-based protocol instead of I2C. On the EVQ7225, the TX and RX pins come from the TJA1057 CAN transceiver which is connected to the differential DATA+ and DATA- pins on the MPQ7225. There is more information about this interface on pages 31 and 32 in the MPQ7225’s datasheet.

Best,
Isabella
