Single reference doc for every component: datasheet title/doc#/rev, source URL, and the
pinout/key specs verified during capture (so it stands alone). PDFs are copyrighted ->
kept git-ignored in hardware/datasheets/ (11 downloaded during this work: RP2350 hw-design,
PCM5102A, THAT1240/1646, OPA1641, TPS65131, TPS7A4901/3001, ULN2003A, TQ2SA, PAM8302A).
Manufacturer-direct hosts (Diodes/ST/onsemi/Winbond/Micro Crystal) block automated fetch --
their URLs are listed for manual download. Also lists tools (KiCad/SKiDL/ngspice) + the
MIDI/USB/balanced-audio standards referenced.
