CAN / RS485
- Both CAN and RS485 communication functions based on UART
- Based on software serial UART - https://github.com/plerup/espsoftwareserial
- RS485 Test code - https://github.com/Edragon/Arduino-ESP32/blob/master/Sketchbook/interface/RS485-1/RS485-1.ino
- RS485 interface connected via IO16/IO17
- CAN interface connected via IO22/IO23
- Change the backside jumper for RS485 can switch to UART0 RXD0/TXD0, but it is used by USB-TTL bridge on ESP32 DEVKITC board.
Programmer LED and Power Supply Read
- One extra programmerable LED indicator – IO5
- One extra power supply voltage read – IO33
