3 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*40mm
5 Weight : 240g
Note: 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 switch
PLC digital analog IO expansion board
I2C SPI input and output controller
RS485 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.
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 support
NOTE : 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
