ESP32 Controller Module with RS485 I2C SPI Support MQTT ESP Home Compatible for Arduino DIY PLC Industrial Automation (DC 12V)

ES30F27 is a multi-function IO expansion board based on ESP32. It has rich IO resources on board, and has independently led out RS485 I2C SPI and 7 ADC ports. And these ports are clearly marked. Using this board, you can easily develop your smart home controller with MQTT HTTP WIFI protocol.Note: This board cannot work independently, must be under the control of the 30PIN ESP32 board to work,If you do not have a ESP32 board, purchase it separatelyDescription:1 Working voltage: DC 12V/24V2 Operating Current : Standby current 15MA, Standby current 52MA (Digital tube ON), 1 relay open 77MA, 2 relays open 106MA, 3 relays open 134MA, 4 relays open 165MA,5 relays open 185MA, 6 relays open 213MA, 7 relays open 258MA, 8 relays open 300MA3 On-board resources: 1x RS485 Interface 8x 10A relay outputs,8x opto-isolated inputs (low level trigger, NPN type), 1x I2C,1x SPI,7x ADC,1x LED,1x Button,1x30PIN ESP32 slots.4 Size 175*90*40mm5 Weight : 240gNote: ES30F27 is an expansion board and cannot work alone. You need to prepare your own ESP32 board and program it.As long as you write ESP32 code,You can use it to achieve a variety of delay timer function,such as:WIFI remote control switchPLC digital analog IO expansion boardI2C SPI input and output controllerRS485 Master-Slave Device(PLC MCU),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.Please contact me for details after purchase!This is an expansion board based on 30PIN ESP32 Board. We only provide some Arduiuo codes for testing the hardware. More codes and functions need to be developed by yourself.ESP32 can be developed using ESPhome, and can develop the following but not limited to WIFI HTTP MQTT Modbus and other protocols (we do not provide these routines, you can find relevant learning materials on the ESP32 official website)If you need more functionality, write your own code. We do not provide additional code and technical supportNOTE : Please use this specification ESP32 board:1 30PIN IO;2 Pin width 25.4MM (board width about 28MM)Note: ES30F27 can not work independently, must be under the control of the 30PIN ESP32 board to work,If you do not have a ESP32 board, purchase it separately
