Overview
Cartouche drive is an open-source printed circuit board by opencorp2030-ctrl, from the opencorp2030-ctrl/cartouche-eclair-proto repository on GitHub. It is a 4-layer board of 36 × 46 mm with 71 parts on 96 nets, routed with 672 tracks and 308 vias.
It is built around the JMS583-QI and TPS82130SIL. Its parts include 46 capacitors, 16 resistors, 3 ICs, 2 connectors and 1 diode.
Main components

README.mdCARTOUCHE Drive
A small USB-C drive for an M.2 2230 NVMe SSD, built around the JMicron JMS583 bridge (USB 3.2 Gen 2, 10 Gb/s → PCIe Gen 3 ×2). It is the prototype drive for CARTOUCHE, a local AI that runs from a USB drive.
Status: schematic v0.1 (ERC 0). PCB v0.4 — 36 × 46 mm, 4 layers (In1 GND, In2 GND + 1.0 V island), 9 high-speed pairs as straight coupled pairs. Impedance from a 2D field solver (tools/impedance.py, JLC04161H-7628, with solder mask): USB 3.2 pairs 0.20/0.10 mm ≈ 86 Ω (target 90 Ω ±10 %), PCIe and REFCLK pairs 0.30/0.20 mm ≈ 89 Ω (target 85 Ω ±15 %), GND stitching. DRC: 0 unconnected, 0 schematic mismatch, 2 silkscreen warnings. Fabrication files in hardware/fab/ (Gerbers zip, JLCPCB BOM and CPL). Prototype, not verified: JMS583 must be consigned (0 stock at JLCPCB), CPL rotations to check in the JLCPCB viewer, LED polarity assumed active-low.

Questions
How big is the Cartouche drive PCB?
It measures 36 × 46 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cartouche drive use?
71 parts, built around the JMS583-QI and TPS82130SIL. 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 Cartouche drive KiCad files?
From the opencorp2030-ctrl/cartouche-eclair-proto repository on GitHub, at the commit this page was made from: the board is hardware/cartouche-drive.kicad_pcb and its schematic hardware/cartouche-drive.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cartouche drive design in my own project?
Its repository states no licence, so its author keeps all rights: ask opencorp2030-ctrl before reusing the design.
