Left and right part connects to the main powerboard with nice!nano (or any another pro micro pinout MCU).
MCU file configuration
To be able to use the nice!nano (or any other MCU with nRF52840) and KMK, it's needed to flash the MCU with CircuitPython and then compile the kmk library

Questions
How big is the Mgkb48 PCB?
It measures 287.3 × 103.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mgkb48 use?
100 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.
Where can I download the Mgkb48 KiCad files?
From the BacaR00T/MGKB48 repository on GitHub, at the commit this page was made from: the board is KiCad/mgkb48.kicad_pcb and its schematic KiCad/mgkb48.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mgkb48 design in my own project?
Its repository states no licence, so its author keeps all rights: ask BacaR00T before reusing the design.
