13 Keys simple macropad
13A Pro is an open-source printed circuit board by PRIMogEnitus, from the PRIMogEnitus/13A-Pro repository on GitHub, published under the MIT licence. It is a 2-layer board of 81 × 81 mm with 30 parts on 36 nets, routed with 103 tracks and 0 vias.
Its parts include 14 diodes, 1 IC and 1 switch. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.
A simple 13-keys macropad, created with the aim of maximum functionality with relatively low cost to build,
And yes the "Pro" in the name stands for nothing, i typed it wrong, and i'm too lazy to change everything again.
13A Pro features small and compact size to carry almost anywhere without sacrificing its functionality, the main downside is that the 13A Pro doesn't have a soft reset key, despite that as it's using Arduino as the MCU, the layout is customizable depending on needs.
Standard layout for the 13A Pro (the first layer is the top legends, where the second layer is the bottom legends)
The 13A Pro macropad hasn't tested yet, so if you decide to build one, then proceed at your own risk.

It measures 81 × 81 mm and has 2 copper layers, 1.6 mm thick.
30 parts. 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.
From the PRIMogEnitus/13A-Pro repository on GitHub, at the commit this page was made from: the board is 13A-Pro.kicad_pcb and its schematic 13A-Pro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
