From the project
CARTOUCHE Drive prototype - USB 3.2 to NVMe 2230 (JMS583). All rights reserved: published for information only, manufacturing forbidden.
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…
