Reminder:

1 Although ESS3A22 has a fully enclosed shell, it is recommended to remove the shell to develop the code during the development stage, and then cover the shell after the development is completed

2 Although the board has an ''ESP32 S3 N8R2'' core board, it is still recommended that you prepare an ESP32 S3 core board so that you can replace the board at any time when the core board fails.



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

WIFI Current and voltage collection

RS485 Master-Slave Device(PLC MCU),

4x 0/4-20MA Current Collection,

4x 0-5V/10V Voltage Collection,

8x 3.3-24V NPN Digital sensor acquisition

6x 85-265V Home appliance control

4x 5-30V LED dimming, or low-power motor speed regulation

MQTT,HTTP,WEB Remote control switch

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 44PIN ESP32-S3. 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:

The ESS3A22 expansion board only supports the ESP32 S3 core board with a width of 44PIN and 28MM. The expansion board comes with an ESP32 S3 core board, but the ESP32 S3 board is more easily damaged during the development process, so it is recommended to prepare your own ESP32 S3 core board.
