Description:

This Module is an USB adapter /programmer for ESP8266 modules of type ESP-01 or ESP-01S. It is conveniently fitted with a 2x4P 2.54mm female header to plug the ESP01. Also it breaks out all the pins of the ESP-01 via a 2x4P 2.54mm male header, so it is very convenient for user to debug the ESP8266.


The module is based on the USB-UART CP2104 which is compatible with all platforms. Onboard with the ESP8266 automatic download circuit. It is very convenient for users to download ESP-01/01S program, upgrade firmware, serial debugging and so on. It supports lots of software such as Arduino IDE, ESP8266 Flasher and Lexin FLASH_DOWNLOAD_TOOLS .

Specification:

  • USB Type A interface.
  • One 2x4P 2.54mm female header
  • One 2x4P 2.54mm male header
  • Operating Volatge: 3.3V
