LilyGO ESP32 CAN RS485

The LilyGO ESP32 CAN RS485 is an ESP32 development board from LilyGO that adds CAN bus and RS485 interfaces to the ESP32's built-in Wi-Fi and Bluetooth. One small board can read data from industrial devices, vehicles and controllers and send it to a network or the cloud, which makes it a good base for Modbus RTU gateways, CAN bus loggers and industrial IoT projects. It is programmed with the Arduino IDE, PlatformIO or ESP-IDF.

What's in the Box

• 1 × LilyGO ESP32 CAN RS485 board

Tip: CAN and RS485 are two-wire differential buses: connect CAN H to H and L to L (A to A and B to B for RS485), share a common ground, and fit a 120 Ω termination resistor at each end of a long bus. Check LilyGO's pin map for this board before setting the CAN and RS485 pins in your sketch.
