Rev 3.1. Fab set 30x30-Rev3.1, verified against board and schematic before
release: the shipped Rev3 export matched no committed board state, this one
is checked mechanically (check_export.py).
Changes since rev3:
- Bulk decoupling bank: 52 x 10 uF 1206 on +BATT/GND, 49 of them PCB-only
(only C2, C3 and C6 exist in the schematic; 24 added since rev3). The
schematic is deliberately not the BOM for these; the fab set carries all 52. - Board setup normalised to the line standard. Zero DRC errors.
- Flashing and QC fixture projects added to the repo.
EMC relevance (technical file): input PDN decoupling changed; switching
topology, clocks and I/O filtering untouched.
