Purchase Notes:

1 ES32A08/ES33B08 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 ESP32

2 This is an expansion board based on 38PIN ESP32. We only provide three vscode codes for testing the hardware. More codes and functions need to be developed by yourself.

3 If you need more functionality, write your own code. We do not provide additional code and technical support

4 The acquisition accuracy of analog quantities is determined by the ESP32 board. It is recommended to collect multiple times to obtain the average value.


Application examples:
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
home automation/Smart home DIY
RS485 Master-Slave Device(PLC MCU),
4x 0/4-20MA Current Collection,
4x 0-5V/10V Voltage Collection,
Motor forward and reverse,
Timing ON/OFF
Power-up Delay,
Trigger delay,
Infinite loop delay,
A finite number of cyclic delays,
Power sequencer,
And so on.
