README
Laptop mods/framework_mobo_lefthalf/README.mdFramework Display Shim
This is a start for reimplementing the Framework Mainboard. Currently, this board is a USB-C DP altmode to Framework display adapter, using the same connector and pinout that the Framework mainboard uses.
This adapter is currently going through the testing process, with a number of fundamental fixes scheduled for the v3 version.

Notes
- This board is untested and there's no guarantees of fitness.
- I recommend a stencil for assembling this board.
Info
- Software: Kicad 7
- Version: 2
- PCB size: w*h
- Layer count: 6
- Recommended thickness: 0.8mm/1mm (needs to match Framework mainboard thickness)

Questions
How big is the Parallel eeprom reader PCB?
It measures 44.2 × 37 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Parallel eeprom reader use?
41 parts, built around the AMS1117-3.3 and CJ2305. 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 Parallel eeprom reader KiCad files?
From the CRImier/MyKiCad repository on GitHub, at the commit this page was made from: the board is Reverse-engineering/parallel_eeprom_reader/parallel_eeprom_reader.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Parallel eeprom reader 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).
