ESP8266 ESP-01 Adaptor Module 3.3V/5V

( MISC )
SG$2.70


To use the ESP8266 with Arduino requires logic level translation of the UART signal, which is provided by this easy to use, 3.3 V - 5 V adapter. The module can be used with Arduino UNO R3 or compatible board without needing an additional level converter, as it is integrated in the module.

The module has Vcc, GND, TX and RX, so it means it uses a serial protocol for Arduino communication (and you will need two pins in the Arduino). Other pins in the ESP-01 are not needed in this scenario.

Adapter module for ESP-01 Wi-Fi module

  • 3.3 V voltage regulator circuit & onboard level conversion for easy use of 5 V microcontroller with ESP-01 Wi-Fi module
  • Compatible with UNO R3
  • 4.5 ~ 5.5 V (on-board 3.3 V LDO Regulator)
  • Interface logic voltage: 3.3 V / 5 V compatible (on-board level shift)
  • Current: 0 - 240 mA
