ESP32 IoT Development Board RS485/Ethernet/Wi-Fi MQTT Protocol High Precision ADC/DAC for Industrial Automation & Smart Home (with Shell)

ES32G15 is a multi-function expansion board for ESP32-DevKitC designed and produced by eletechsup. It has a variety of analog and digital input and output circuits including NTC. To facilitate development, we have printed the mapping of each output pin on the back of the PCB board.1 Working voltage: Wide voltage DC 12-28V2 Working Current : Standby current 15MA, 1 relay open 50MA, 2 relays open 85MA, 3 relays open 120MA, 4 relays open 155MA3 size 121*72*19mm(Only Board)4 Weight : 95g(Only Board), 186g(with shell)Onboard Resources 2CH 0/4-20MA Current Output2CH 0-5V/10V Voltage Output2CH 0/4-20MA Current Input2CH 0-5V/10V Voltage Input4CH 10K NTC Input(Any B value)4CH NPN Digital Input4CH 10A Relay Output5CH Free Port1CH RS485 Port This is an expansion board based on 38PIN ESP32( ESP32-DevKitC). We only provide some Arduiuo codes for testing the hardware. More codes and functions need to be developed by yourself.If you need more functionality, write your own code. We do not provide additional code and technical support Note: ES32G15 can not work independently, must be under the control of the 38PIN ESP32 board to work,If you do not have a 38PIN ESP32 board, purchase it separately or purchase a kit with 38PIN ESP32
