This CAN bus operates at 125kbit/s. The module is connected via SPI and currently requires a separate SPI bus. If you want to use the Huawei AC charger make sure to get an ESP which supports 2 SPI busses. Currently the SPI bus host is hardcoded to number 2. This may change in future. Please note: Using the Huawei AC charger in combination with the CMT2300A radio board is not supported at the moment. - -MCP2515 CAN bus modules that are widely available are designed for 5V supply voltage. To make them work with 3.3V / the ESP32 a modification is required.
