KS0386 Keyestudio ESP-01S Wifi Module Adapter Board for Arduino
Introduction
This is an expansion board for the ESP-01S WiFi module, compatible with the breadboard. You can directly plug the ESP-01S module according to the arrow silk-screen onto the board, and plug them into the breadboard. The ESP-01S module adapter board allows easy connection for experiments through the breadboard plug. After power-on, the module is in BOOT flash mode, and the AT command test can be directly performed.

Use Method
1) AT Command Settings
When testing the AT command, you should use a USB to Serial module, that is FT232 module, an ESP8266 WIFI module, and a breadboard.
Connect well and then connect them to your computer using mini USB cable.
Connected successfully, open the ESP8266 debugging tool, set the baud rate to 115200, click to open the Serial Port, and click Test the AT. You should see the data received window will print out AT OK.
To set other AT commands, the method is similar.
