README

This repo contains all relevant documentation of the cartridge hardware.
The legacy directory contains legacy documentation.
This is just a collection of documents I made waaaay back when I was
just starting on the project.
It is included here just as an archive so I don't plan on updating anything.
The CartGen3ProtoBoard directory contains the schematics for the
first working prototype mentioned at my website.
The photograph below is this prototype.
The CartGen4 directory contains the schematics for the
next prototype.
I've included some renders of it below.

gen4-render-back
Development tools
The tools used to make the schematics is KiCad.
It can be used to open the *.kicad_pro file to open the schematic
project.

Questions
How big is the CartGen4 PCB?
It measures 52.7 × 60.9 mm and has 4 copper layers, 4 mm thick.
What parts does the CartGen4 use?
86 parts, built around the LFXP2-8E-5MN132C, AS1C8M16PL-70BIN, IS25WP080D-JNLE and MEM2080-00-128-00-A. 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 CartGen4 KiCad files?
From the elialm/ecgc-hardware repository on GitHub, at the commit this page was made from: the board is CartGen4/CartGen4.kicad_pcb and its schematic CartGen3ProtoBoard/CartGen3ProtoBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CartGen4 design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
