Development Boards

Top view of an Adafruit Metro, Circuit Playground, Feather, and Trinket

The development board category is DIY's beating heart. These are the boards that pump liquid solder through your project's veins and keep makers pushing boundaries, breaking down barriers, and finding creative solutions based off of the myriad microprocessors these boards are built around.

Whether you're looking for a hot-off-the presses Adafruit original, or trying to build out your Arduino-compatible collection, or are just a Feather completest - Development Boards are where Maker projects and DIY innovation begin!
