Overview
PiSurf is an open-source printed circuit board by johnnyb, from the johnnyb/SurfBoard repository on GitHub. It is a 2-layer board of 65 × 56 mm with 7 parts on 40 nets, routed with 139 tracks and 0 vias.

Motivations
This is a collection of hardware boards aimed at creating stackable headers for custom modules.
When putting together projects, I found that there are a lot more modules than HATs/Shields/whatever. What would be nice would be just a plain PCB that had the following:
- The stackable headers in the right place for the form-factor
- Through-hole soldering points which connected to the stackable headers
- A blank PCB on top that provides a surface to hot-glue a module to
- Traces all along the back so that they don't interfere with whatever you attach
The original impetus for this was finding a 12V->5V conversion HAT for a Pi. For some reason, they just don't exist. There are innumerable buck converter modules that do this, but none as a Pi HAT. Most power modules for the Pi are either doing something else or way over-complicated. I just wanted a 12V input (to connect to a car power system) converted to the 5V input pin on the Pi.
So, I originally did it on a regular PCB, but later decided that I wanted to make a board to simplify things.
Example
Below is the first board - the PiSurf - with a power module attached.

Questions
How big is the PiSurf PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PiSurf use?
7 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 PiSurf KiCad files?
From the johnnyb/SurfBoard repository on GitHub, at the commit this page was made from: the board is PiSurf/piSurf.kicad_pcb and its schematic PiSurf/piSurf.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PiSurf design in my own project?
Its repository states no licence, so its author keeps all rights: ask johnnyb before reusing the design.
