Expansion Board
This is a project template for a Raspberry Pi B+ Hat.
This base project includes a PCB edge defined according to this specification. Both a thru-hole and a surface mount connector are provided, along with a different PCB edge for each. Just keep the PCB edge and connector type that you're using for your design and delete the others.
The component footprints used in this template are here.
The board outline looks like this:
Using the Template
To use the Raspberry Pi Hat template with the through-hole connector, do the following:
- Open the schematic. Remove the SMD connector, J1.
- Generate the schematic netlist.
- Generate the .cmp file. (The J2 connector will be the only component in it.)
- Open the PCB. Hover your mouse over the connector and hit e to edit it. Select the J1 SMD connector. In the Move and Place section of the Footprint Properties window, select the Free radio button. Then click OK. The SMD connector should now be unlocked so it can be removed.
- Read in the netlist from the schematic. In the Extra Footprints section of the Netlist dialog window, select the Delete radio button. Then click Read Current Netlist. The J1 SMD connector should disappear. Then click Close.
- Finally, delete the upper two arcs and the edge of the board outline.

Questions
How big is the RPi Hat PCB?
It measures 65 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RPi Hat use?
12 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the RPi Hat KiCad files?
From the wrongbaud/RPi_Hat_Template repository on GitHub, at the commit this page was made from: the board is RPi_Hat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RPi Hat design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
