Work exactly as they should

I played around with this for fun and found it easy to use. I really liked using jumpers to change i2c addresses - much easier than cutting and soldering traces. It is also nice that they can be easily connected via plug connections.

Pros
  • Standard interface that can be extended to different development boards
Cons
  • Is there anything I can add
