This little milling machine is great for quickly making prototypes of PCBs and parts. In this guide we'll take a look at the process of milling double-sided PCBs. In this project, we'll make a breadboard adapter for the Adafruit Circuit Playground.

Connecting Things to Circuit Playground Express 

Circuit playground express is a great board with lots of sensors and components. There’s lots of example projects, libraries and code on the Adafruit learning system.

There’s certain projects where you need to connect other components like motors and servos. Using alligator clips is a nice solder-free way to connect things but not always the most robust.

Fabricating a custom PCB adapter with standard 0.1" headers is a great way to attach jumper cables and other connectors Circuit Playground Express.

DIY Perfboard Shields

Dave Astels’s learn guide shows how to make your own breadboard adapter using perf board, standoffs and screws. This allows you to simply plug-in jumper wires making a much more sturdy connection. You can purchase the Circuit Playground Breadboard Biscuit by Dave on Tindie.
