Breadboard adapter for ESP8266 module




ESP8266 is an inexpensive serial-to-wifi tranceiver chip that allows to connect any microcontroller with a serial port to a WiFi network. Because of its simplicity and low cost, it is getting popular among hobbyists for building Internet of Things (IoT) applications.

While there are varieties of breakout boards available for ESP8266 from the Chinese markets, the most popular one is the ESP-01 version that provides access to the ESP8266 pins through a 2×4 male header. While the headers are 0.1″ pitch, the pin arrangements are not breadboard friendly and are not labeled on board, which makes it little inconvenient for breadboarding. I have designed a very simple breadboard friendly adapter (shown below) with clear pin labels printed on the board to make prototyping with the ESP-01 module easier.
