What's this?
This is the repo for my macropad! It was made for the hackpad ysws! It uses a XIAO-RP2040-DIP as the mcu and is currently very wip.
[!WARNING] This is a work in progress and is not yet ready for use. listen to the warning 💀 🏴☠️

Questions
How big is the Quant PCB?
It measures 59.4 × 82 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quant use?
16 parts, built around the SK6812MINI-E. 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 Quant KiCad files?
From the taciturnaxolotl/quant repository on GitHub, at the commit this page was made from: the board is kicad/quant.kicad_pcb and its schematic kicad/quant.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quant design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
