## 40-pin Expansion Board

This project template is the basis of an expansion board for the Raspberry Pi ARM boards that have the 40-pin header.
This includes the following models to date:

- Pi 1 A+
- Pi 1 B+
- Pi 2 Model B
- Pi 3 Model B

This base project includes a PCB edge as specified in the Raspberry Pi Hat Specification with the connectors placed correctly to align the two boards. All IO present on the Raspberry-Pi board is connected to the project through the 0.1" expansion headers. Cutouts have also been defined for the camera and the display connctors.

The board outline looks like the following:
