ESP8266 / NRF24L01 Breadboard Adapter

Have you ever been anxious to receive your new break-out boards, only to find out that the pin layout is not breadboard friendly? If only those pins were aligned differently.

Well, let me show you how I have made an easy breadboard adapter that will fit the nRF24 or ESP8266 boards. No modifications or soldering is required on the modules itself.

Step 1: Preparing the Components

You will need a piece of veroboard, and some headers and pins.

  • Cut a piece of veroboard into a 4 x 4 hole square (or the size you require).
  • Use a very sharp cable or hobby knife to cut the strips in between the center of the holes as shown in the picture.
  • Cut two headers from the strip, each with 4 sockets.
  • Cut two rows of pins, each with 4 pins.
  • Using long nose pliers, press the pins flush with the plastic holding them together.

Step 2: Assembly of the Header Connectors

  • Place the 2 headers on the board.
  • Insert extra pins into the headers. This will keep them aligned during soldering.
  • Solder the headers to the board.
  • Remove extra pins used for alignment.
  • After soldering, ensure that there are no shorts between the pins.

Step 3: Assembly of the Pins

  • Insert the pins from the top of the board so that the plastic is flush with the board.
  • Use spare headers to keep the pins aligned during soldering.
  • Solder the pins to the board.
  • Remove spare headers used for alignment.
  • Again, ensure that there are no shorts between the pins.

If all went well, your adapter should look similar to the photos.

Step 4: Using the Adapter

The adapter will now fit snugly into the breadboard, leaving enough room for your connections or wires. After all the connections are done, simply insert the ESP8266 or nRF24 module into the adapter.

    This also gives a good to connect the 4.7µ - 47µF capacitor (if you are having communication problems) if you use off bread board.

    Brill having done similar to connect icsp when programming attiny never thought of this for the nrf. Thankyou

    Finally! After seeing all this 'adapters' where the modules get mutilated beyond being useful for anything else, I was almost on the edge to do it right. Well, you were faster.

    Nice write-up, good pictures, I tip my hat (if I would wear any, that is ;-) ).
