ESP32 Development Kits with Onboard CAN Bus Controller

The ESP32 includes a CAN Bus controller compatible with the NXP SJA1000, making it compliant with the CAN 2.0B (ISO 11898, also known as Classical CAN) specification.

Nevertheless, as with the SJA1000, the ESP32 CAN Bus controller only provides the data link layer and the physical layer signaling sublayer. As a result, an external transceiver module is needed to convert the ESP32's CAN-RX and CAN-TX signals into CAN_H and CAN_L bus signals.
