Overview
Minister is an open-source printed circuit board by makenova, from the makenova/minister_e repository on GitHub. It is a 2-layer board of 271.5 × 88.1 mm with 112 parts on 88 nets, routed with 981 tracks and 112 vias.
It is built around the ATMEGA32U4-AU and PRTR5V0U2X. Its parts include 47 diodes, 7 capacitors, 6 resistors, 1 IC and 1 connector. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

README
README.mdMinister_E
Minister_e is a hot swap 40% with a centered USB port and the layout of the prime_e V2. I made this because the designer of the prime_e had no intention of making a hot swap version of the V2 PCB and I wanted one.
The step file can be found in the docs folder.

Questions
How big is the Minister PCB?
It measures 271.5 × 88.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minister use?
112 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Minister KiCad files?
From the makenova/minister_e repository on GitHub, at the commit this page was made from: the board is minister.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minister design in my own project?
Its repository states no licence, so its author keeps all rights: ask makenova before reusing the design.
