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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
