Specs
- STM32 F072 MCU
- JST SH or Molex EZMate Pico headers
- ESD and overcurrent protection
- Meme cut
- Other stuff like diodes (the cool ones)
Todo
- Confirm prototype works electronically
- QoL improvements and case fit
- Generic silk with revision number
- Misc. cleanups
- A la carte gerbers for connector options (JST or EZMate)
- Use git submodule for parts lib

Questions
How big is the Tiny Dimply Qazy PCB?
It measures 200 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tiny Dimply Qazy use?
93 parts, built around the USBLC6-2SC6, BAV70 and SMF9.0CA. 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 Tiny Dimply Qazy KiCad files?
From the ASH-ART/Tiny-Dimply-Qazy repository on GitHub, at the commit this page was made from: the board is PCB Files/Tiny Dimply Qazy.kicad_pcb and its schematic PCB Files/Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tiny Dimply Qazy design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
