README
README.mdInky - An E-Ink badge
This is an e-ink USB-C PCB badge that I'm building since I loved the Github one so much, and want to make my own! I decided that I wanted to follow a similar design route with the Github Badge so I went with the RP2040 IC.
This was my first time designing an FPC cable from scratch on a PCB! Originally, I wanted to do it to help make a board for my brother, but in the end, I found it too complicated. For this board, I decided to use Gemini to help me, since I wasn't able to find any good documentation of how to properly wire it up.
When I first started this, I though it would take at least 10 hours from when I glanced at the Github Badge, but in the end, it only took me about 4.3 hours which was insanely quick and efficient of my time!
I have attached some photos below outlining the PCB, Schematic and even the 3D rending's on the board!

Questions
How big is the E Ink badge PCB?
It measures 61.7 × 46.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E Ink badge use?
40 parts, built around the RP2040, W25Q16JVSSIQ, AP2112K-3.3 and MBR0530. 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 E Ink badge KiCad files?
From the scooterthedev/E-Ink-badge repository on GitHub, at the commit this page was made from: the board is E-Ink badge.kicad_pcb and its schematic E-Ink badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E Ink badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask scooterthedev before reusing the design.
