README
README.mdStarboard
The Starboard is a 4 layer USB C devboard that I made using a PY32 chip. It has two 9-pin headers, each offering VBUS, +3.3V, and GND along with 4 IO pins, NRST, and BOOT. Along with this it offers the ability to use a microSD to store code for the devboard. Currently I have not made the physical pcb for this. Currently only the files exist.

Questions
How big is the PY32 Devboard PCB?
It measures 38.5 × 48.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PY32 Devboard use?
24 parts, built around the PY32F002BF15P6TR, CH340N and ME6211A33M3G-N. 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 PY32 Devboard KiCad files?
From the Asurant/Starboard repository on GitHub, at the commit this page was made from: the board is src/kicad/PY32_Devboard.kicad_pcb and its schematic src/kicad/PY32_Devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PY32 Devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Asurant before reusing the design.
