This mod draws heavily from lightcreations's TI-84 USB-C mod. I basically took their work and spent 20 minutes editing the footprint for compatibility with the Nspire.
As I outlined in both of my previous NSpire USB-C mods (links here and here), the pinout on the NSpire is different than on the TI-84, so the mod needs to be done slightly differently.
I swapped the relevant pins on the PCB to match the NSpire's footprint, and I also added a silkscreen label to differentiate this version from the TI-84 version. Below are front and back screenshots of the PCB.
While this board should work in theory, the left side of it will be extremely close to the LED indicator, as seen below.
This may make it necessary to make a slimmer version 2 of this board, but we'll cross that bridge when we get there. For now it should work as is, and I'll update this repository with any information once I've got the boards in.
