Pinout corrected (0.1.1)

Ray · 4h ago ·closed by Ray

The published pinout differed from a better-checked source on 2 of 16 pins.

Fixed in 0.1.1: pinout replaced from review decision: ray (review) (). The footprint's pads match it; page.json, README pin table, KiCad symbol (regenerated), Fusion .lbr and viewers updated. Descriptions were kept where the pin name matched.
