Every Adafruit board needs a tester to ensure that the hardware works before it's placed in the Adafruit store. These testers generally consist of a board with a pre-programmed microcontroller to administer the test, and an array of spring loaded contacts, often called "pogo pins", to mate with the device under test.

Are you doing your own small scale manufacturing?  Do you just want to get your code working before soldering headers on that FeatherWing?  Either way, this guide is for you.

In this guide, you'll learn how to make your own tester for Feather/FeatherWing form factor boards.

Be prepared to heat up your 3D printer and your soldering iron for this project!

Parts
