ℹ Important information regarding compatibility

Please note that this module is a transceiver and requires a CAN controller to function properly. The ESP32 microcontroller has a built-in CAN controller, while other boards (such as Arduino, ESP8266, or Raspberry Pi) do not and require an additional, external CAN controller (e.g., MCP2515).
