So, my proof of concept CircuitPlayground shield works. The concept was proved. What was the next step? Custom PCBs, naturally!
I spent New Years Day evening designing 3 different shield PCBs:
- A breadboard shield exactly like the prototype outlined here.
- A very similar shield with a 2x14 header rather than 2 1x14 headers. This is meant to connect a cable.
- A prototyping shield with a standard 0.1" spaced grid of holes..
This mix allows you to prototype on a breadboard, use the CircuitPlayground on the outside of a box with more hardware inside, or put some hardware directly on the shield.
