ESP32 RS485 (Modbus) Controller Reference Design

ESP32 RS485 (Modbus) Controller Reference Design thumbnail
This project is a controller module that uses the ESP32-WROOM-32E and the MAX3485 to communicate with Modbus devices. It has a USB-C port for power and data, a voltage regulator for stable operation, and headers for connecting sensors and actuators. It also has a CH340C chip for USB to serial conversion. #referenceDesign #project #ESP32 #ESP32WROOM #RF #WIFI #MCU #referenceDesign #simple-embedded #espressif #template #MAX3485 #RS485 #maximintegrated #reference-design
