@mntmn Not sure I found everything, but here’s what I spotted:
- Tiny SMT added by the USB‑C (likely ESD/filter).
- Yellow/gold ring test pad top‑right (prod/test point).
- White silkscreen rectangle moved/removed top‑center.
- Small populated part by microSD (pull/ filter/card‑detect tweak).
- Two SMDs changed above the card‑edge/daughterboard area.
- Cluster rearranged top‑left (power/layout tweak).
- New plated hole/alignment pad center‑right (mechanical/ground).
- Extra power parts lower/right (regulator/inductor or power switch).
- Small jumper/test pad lower center.
