Hello. I'm a Pi Crust.

I connect electronics to your Raspberry Pi.

What am I?

I'm a breakout board for the Raspberry Pi. I make it easy to connect electronics.

About the Design

The toughest part of my design was making me fit inside a Raspberry Pi. The existing Raspberry Pi headers actually go all the way through my board and I sits approximately 2mm above the Raspberry Pi (very close). It's almost as if I'm part of the original board.

Because I sit so close to the Raspberry Pi, care has been taken to ensure that my thru-hole components avoid components on the Raspberry Pi board (so they don't short them out), and to avoid restricting air getting to the main ARM processor.

Get the Parts

You can order the parts and assemble it yourself. If you can do basic soldering, you're all set. It's very easy: here's how...

Don't know how to solder? It's really easy. Check out the Soldering Is Easy comic.

Drew Fustini noticed that the Adafruit Real Time Clock module has the same I2C pin ordering. You can slot it in directly.
