Note: ES30E08 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

ES30E08 is eletechsup's first 30PIN ESP32 expansion board with a shell. Onboard resources include ESP3 slot/RS485/8DI/8Relay/1Button/1LED. This expansion board can be used as a DIY WIFI smart home controller or as a RS485 master-slave device.

Description:

1 Operating voltage: DC 12V/24V

2 Operating Current : Standby current (Digital tube OFF) 13MA, Standby current 51MA (Digital tube ON), 1 relay open 76MA, 2 relays open 107MA, 3 relays open 133MA, 4 relays open 166MA,5 relays open 185MA, 6 relays open 213MA, 7 relays open 258MA, 8 relays open 290MA

3 On-board resources: 1x RS485 Interface 8x 10A relay outputs,8x opto-isolated inputs (low level trigger, NPN type), 1x LED,1x Button,1x30PIN ESP32 slots.

4 size 144*90*40mm
5 Weight : 220g

Note: ES30E08 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
8x RS485 DI-DO
RS485 Master-Slave Device(PLC MCU),
Motor forward and reverse,
LED Controller
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.
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)
