README
Electrical/SpringAdapter/README.mdInput Module Adapter
This is a simple USB-C adapter to use and develop Input Modules outside of a Framework Laptop 16. Note that the actual pogo pin connector is a custom Framework part. We originally created this to enable Input Module development ahead of Framework Laptop 16 shipments starting. Now that Framework Laptop 16 has been available for a few years, this design is mostly for reference for anyone who wants to build projects around Input Modules.

Assembly and Fabrication
We recommend using a 0.8mm PCB for this due to the specific USB-C connector we selected (for hand-solderability). To make Input Modules attach to the adapter, you can glue in 5mm x 2mm cylindrical magnets or glue on 5mm x 5mm x 1.2mm square magnets. You can use 6mm M2 fasteners as the alignment pins.

Questions
How big is the MicrocontrollerInputModule PCB?
It measures 33.8 × 131 mm and has 2 copper layers, 0.96 mm thick.
What parts does the MicrocontrollerInputModule use?
47 parts, built around the RP2040, W25Q16JVUXIQ, KXT3 and SK6812MINI-E. 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 MicrocontrollerInputModule KiCad files?
From the FrameworkComputer/InputModules repository on GitHub, at the commit this page was made from: the board is Electrical/MicrocontrollerInputModule/MicrocontrollerInputModule.kicad_pcb and its schematic Electrical/LEDMatrix/Driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicrocontrollerInputModule design in my own project?
Its repository states no licence, so its author keeps all rights: ask FrameworkComputer before reusing the design.
