Overview
Pcbfiles is an open-source printed circuit board by goldfishgaming33, from the goldfishgaming33/HMS-Byte-Size repository on GitHub. It is a 2-layer board of 95 × 55 mm with 22 parts on 39 nets, routed with 179 tracks and 308 vias.
It is built around the RASPBERRY PI ZERO 2 W. Its parts include 8 capacitors, 3 ICs, 3 connectors, 2 resistors and 1 diode. It belongs with the Raspberry Pi (Linux) boards of this library.

README.mdABOUT
- I decided to take on this project when I realised I had nothing better to do over the summer
- I wanted to make use of skills I learnt while building a different device for a school competition which was a satellite in the size of a can
- I learnt to solder better, code better on the Raspberry Pi platform and design a PCB
- RC models and boats have always interested me, so I decided to combine the two to create HMS Byte Size
- The system will operate on the Raspberry Pi Zero 2W, communicating over 2.4GHz RF with a secondary Pi which will control the boat remotely
- I wasn't too confident with SMD and lacking a hot plate or any SMD capability, I decided to go with all through hole components
LED will power to confirm the board is running
Careful planning of how to power such project took place and resulted in numerous de-coupling capacitors, and others to manage current spikes and back-EMI
2-layer PCB composed of all through hole components, will full layer ground pours, and via stitching
Compact 3D printed design for easy assembly
Costs
It's looking rather costly
I've tried to stick to amazon and ali express for cheap components, but obviously I have doubts about reliability and whatnot.
Things like resistors and capacitors through MouserUK and RapidElectronics
BOM
It's a bit messy, I just add as I go. All accurate though

Questions
How big is the Pcbfiles PCB?
It measures 95 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcbfiles use?
22 parts, built around the RASPBERRY PI ZERO 2 W. 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 Pcbfiles KiCad files?
From the goldfishgaming33/HMS-Byte-Size repository on GitHub, at the commit this page was made from: the board is pcbfiles/pcb.kicad_pcb and its schematic pcbfiles/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcbfiles design in my own project?
Its repository states no licence, so its author keeps all rights: ask goldfishgaming33 before reusing the design.
