From the project
Tiny USB4 (40 Gb/s) NVMe 2230 drive board (22 x 34 mm) for CARTOUCHE, a local AI you carry in your pocket. KiCad 9, Gerbers, BOM, STEP.
CARTOUCHE is a way to store heavy AI models and run them easily and fast, while keeping your data from going to third-party servers.
I got the idea because I have a lot of other projects with AI, and this was a real problem. I like solving the problems I have.
Why my own drive (Éclair) and not just USB keys: because I want it to be useful for devs and to be a good deal. That's actually why I set up the developer program.
