Embedded Lab

Elecrow is now offering the popular ESP-01 Serial-to-WiFi transceiver module along with our breadboard adapter kit for simplifying the prototyping of the ESP8266-based IoT applications. While you can buy the breadboard kit alone from our Tindie Store, we don’t ship it worldwide. Elecrow offers worldwide shipping at reasonably lower shipping costs.

ESP8266 module and breadboard adapter

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. We have designed this very simple breadboard friendly adapter (shown below) with clear pin labels printed on the board to make prototyping with the ESP-01 module easier.

Breadboard adapter makes prototyping easier

The adapter has a 2×4 female header to receive the ESP-01 module and a 10uF power supply filter on board. The ESP-01 module pins are accessible through two single row headers that are breadboard friendly.
