USB ESP8266 breakout adapter

This adapter connects an ESP-01 or ESP-01S Wi-Fi module to a USB port for serial communication and programming. It provides a compact interface for wireless sensor projects and remote transceiver applications. The board is supplied new and ready for integration into custom electronics builds.

Makers adding Wi-Fi to USB hosts

Developers who need a simple way to add wireless connectivity to a computer or single-board computer via USB will find this breakout convenient. It is not suited for projects that require a different module form factor or an integrated antenna solution not provided by the ESP-01S.

Questions about this item

What USB port does the ESP-01S breakout board plug into?

The board connects directly to a standard USB-A port for power and serial communication with the ESP8266 module.

How is the ESP-01S module seated on the breakout board, and what alignment mistake should be avoided?

Insert the ESP-01S module into the 2×4 header so the antenna end faces the board edge; reversing it connects power to the wrong pins and prevents operation.
