Description:

A adapter module for ESP-01 Wi-Fi module. 3.3V voltage regulator circuit and onboard level conversion circuit can make 5V microcontroller easy to use with ESP-01 Wi-Fi module.

Also, the item can be used with For Arduino UNO R3 or compatible board.

 

 

Features:

Working voltage: 4.5~5.5V (On-board 3.3V LDO Regulator)

=> EPS8266이 3.3v에서 동작하지만, 어뎁터에서는 5.5v에서 동작함. 3.3v를 어뎁터에 공급하면 전압이 낮아 동작하지 않음.

Working current: 0-240mAInterface logic voltage: 3.3V / 5V compatible(On-board level shift circuit)

 

 

Package Included:

1 x ESP-01 Adapter Module

 

 

PS. 아두이노 우노에 사용하려면, ESP8266의 통신속도를 9600bps로 펌웨어 업데이트 해야 함.
