Overview
VRC7 MMC5 is an open-source printed circuit board by Infinest, from the Infinest/Lagrange-Point-PCB repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 99 × 93.9 mm with 16 parts on 89 nets, routed with 1,258 tracks and 212 vias.
Its parts include 6 ICs, 4 capacitors, 1 resistor, 1 diode and 1 crystal.
README
README.mdLagrange Point PCB in an MMC5 cartridge
This repository contains gerber files for a PCB that allows transplanting your copy of Lagrange Point into an MMC5-type cartridge shell. The PCB should fit into both the original shells made by Nintendo as well as these reproduction ones.
All parts from the original PCB can be directly transferred over to the new PCB.
The only new part required is the CR2025 coin cell holder. The part number for it is BK-6219-TR.
The PCB needs to be ordered with a thickness of 1.2mm and the edge connector should optimally be chamfered.

Questions
How big is the VRC7 MMC5 PCB?
It measures 99 × 93.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VRC7 MMC5 use?
16 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 VRC7 MMC5 KiCad files?
From the Infinest/Lagrange-Point-PCB repository on GitHub, at the commit this page was made from: the board is KiCad/VRC7_MMC5.kicad_pcb and its schematic KiCad/VRC7_MMC5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VRC7 MMC5 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
