Overview
Mchck is an open-source printed circuit board by mchck, from the mchck/mchck-board repository on GitHub. It is a 2-layer board of 36.6 × 18.8 mm with 41 parts on 51 nets, routed with 499 tracks and 32 vias.
It is built around the CDBU0530. Its parts include 11 capacitors, 11 connectors, 4 resistors, 4 ICs and 3 diodes. It belongs with the NXP (LPC, Kinetis, i.MX RT) boards of this library.
Main components
1README
README.mdThe MC HCK!
The goal is to have a small, cheap, and powerful development board that supports USB for easy programming, at a low price (current estimate: $7, target $5). This allows us to use the board for all silly purposes where spending >$20 for other microcontroller boards is just too much.
The schematic design and layout was done using KiCad http://kicad.sourceforge.net, a Free Software EDA tool for Linux, Windows and Mac OS. You will need KiCad to open the .sch or .brd files - gEDA or Eagle will not work.

Questions
How big is the Mchck PCB?
It measures 36.6 × 18.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mchck use?
41 parts, built around the CDBU0530. 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 Mchck KiCad files?
From the mchck/mchck-board repository on GitHub, at the commit this page was made from: the board is mchck.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mchck design in my own project?
Its repository states no licence, so its author keeps all rights: ask mchck before reusing the design.
