From the project
USB3 multi-HDD adapter (PATA+SATA) — JLCPCB Gerbers/BOM
Desk/cable adapter: USB 3.0 Type-B upstream, 2× SATA (2.5"/3.5"), 40-pin + 44-pin PATA on one ATA channel, 12 V barrel + Molex. Aimed at JLCPCB (4-layer impedance) + LCSC SMT.
v0.2. Pad-to-pad copper, USB3 hub TX→bridge RX through 100 nF, PATA bus to both IDCs, inner-layer planes only (no shorting F.Cu flood). SuperSpeed is still not TDR-lab verified. USB2 fallback is possible on the first spin.
