Overview
MinimalSmallInputModule is an open-source printed circuit board by FrameworkComputer, from the FrameworkComputer/InputModules repository on GitHub. It is a 2-layer board of 33.8 × 131 mm with 14 parts on 7 nets, routed with 43 tracks and 44 vias.
Its parts include 5 diodes, 2 capacitors, 1 resistor and 1 connector. It belongs with the computers and single-board computers boards of this library.
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 MinimalSmallInputModule PCB?
It measures 33.8 × 131 mm and has 2 copper layers, 0.96 mm thick.
What parts does the MinimalSmallInputModule use?
14 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 MinimalSmallInputModule KiCad files?
From the FrameworkComputer/InputModules repository on GitHub, at the commit this page was made from: the board is Electrical/MinimalSmallInputModule/MinimalSmallInputModule.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 MinimalSmallInputModule design in my own project?
Its repository states no licence, so its author keeps all rights: ask FrameworkComputer before reusing the design.
