“When I upgrade my LED module to an RGB LED module I’d like to have someplace to show off the extra module” (small size module)
Developers or production testing modules
It’s not super hard: the input modules are just USB-C, and we have specs for the connectors, and even a full schematic for a “dev board” which adapters the pogo pins to USB-C. The main task is just designing a suitable (and sleek?) enclosure.
My own contributions here: I’ve started working on a parametric freecad design for the enclosure, which ought to be able to scale from small to medium to large to even theoretically “full scale” (large plus two small) widths.
The electrical part is pretty straightforward other than sourcing the pogo pin connector, which is custom to framework. But I found this on digikey/JLCPCB, which ought to work in pairs:
(The needed connector is 2 rows of 4 pins, spaced 2mm apart in the “4” direction and 3.5mm apart in the “2” direction.)
I haven’t figured out how to source and mount the magnets yet; on my dev board from framework the magnets quickly came unglued and I noticed that Joseph was using clothespins so I suspect the same happened there as well. So some better mounting mechanism is needed (or maybe just better glue).
I’ve designed the PCB and a 3d-printed case for holding two small or one medium-sized input module. It could be scaled down to a single small input module or scaled up to a keyboard module (it’s a parametric design) but this seems like a reasonable starting point. It includes a two-port USB hub (actually four port!) so that two modules can be used simultaneously, but these components can be omitted to make a single-port version.
