DC 12V 24V ESP32 Expansion Board Digital Analog DAC ADC IO WiFi Relay Switch ES32C14 Module for Arduino PLC Smart Home IOT DIY (DC 12V with Shel)

ES32C14 is a multifunctional ESP32 expansion board developed and designed by eletechsup. By inserting it into the ESP32 core board, you can DIY a variety of analog and digital remote IO. Through ESP32 programming, it can become a small PLCProduct Features:1 Operating voltage: DC 12V/DC 24V2 Operating Current : Standby current (Digital tube OFF) 14MA, Standby current 51MA (Digital tube ON), 1 relay open 76MA, 2 relays open 107MA, 3 relays open 133MA, 4 relays open 166MA3 On-board resources: 1x RS485 Interface 4x opto-isolated inputs (low level trigger, NPN type), 2x 0/4-20MA Current Input,2x 0-5V/10V Voltage Input,2x 0-5V/10V Voltage Output(OR 2x 0/4-20MA Current Output),1x ESP32 slots,4x relay outputs4 size 121*72*19mm(Only Board)5 Weight : 94g(Only Board), 183g(with shell)As long as you write ESP32 code,You can use it to achieve a variety of delay timer function,such as:WIFI remote control switchWIFI Current and voltage collectionRS485 Master-Slave Device(PLC MCU),2x 0-5V/10V Voltage Output(OR 2x 0/4-20MA Current Output)2x 0/4-20MA Current Collection,2x 0-5V/10V Voltage Collection,Motor forward and reverse,Timing on,Timing off,Power-up delay,Trigger delay,Infinite loop delay,A finite number of cyclic delays,Power sequencer,And so on.This is an expansion board based on 38PIN ESP32. We only provide some 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 supportNote: ES32C14 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 ESP32Note: Vo1/Io1, Vo2/Io2 are multiplexed output ports, only one of them can be enabled (selected by SW1 dip switch)
