ES38485 ESP32 DevkitC V4 DIN Rail Expansion Board RS485 to WiFi 38PIN PLC HMI Ethernet BLE Smart Home Development Board for IoT Projects

ES38485 is a 38-pin ESP32(Espressif ESP32 DevkitC v4) expansion board with RS485 bus interface produced by ELETECHSUP. It lead out all the useful pins except the 3 ports required for RS485. In addition, it also has a wide voltage step-down circuit and can be powered by DC 7-30V. When plugged into the ESP32 board, it becomes a cost-effective main control board with WIFI and RS485.
