- J1/J2 rotated to vertical rows: J2 (outer) x63.77, J1 (inner) x78.77,
y52.8-101.1 — module hugs the front edge full-length, USB end (J1 pad20
/SYS5V) at the top-front corner; antenna exits directly at the front
- Front edge cleared: P15 (RS-485) -> top edge between MH5/MH1, P16 (RS-232)
-> bottom edge west of the modem pad row, H4 TTL -> top strip next to P5
- RJ45 kept at the bottom-left of the front edge (no other edge window fits
a 19x22.3mm magjack) with the no-pour zone moved under it
- Serial cluster re-laid east of the module; W5500 satellites auto-placed
by greedy collision-free placer; 0 pairwise courtyard conflicts (190 fp)
