Corrections, identifications and measurements from other engineers are what turn one person's teardown into a usable reference. Nothing here is precious — if something is wrong, say so.
Anyone can submit a finding, signed in or not. A free account — the same one as the forum — means your contribution is credited to you automatically, and it is what gets you the full-resolution source imagery. Everything is reviewed before it appears either way.
Three things would improve this site more than anything else:
U25 — QFN-16, roughly 3 × 3 mm,
marked BT5 / 0206 / 947, no logo, sitting between the two
TPS74901 regulators and the SoC on BMDPCB720C.
Everything is reviewed before it appears anywhere on the site. Measurements are published with their conditions attached and credited to you unless you'd rather they weren't. If a correction shows something here is wrong, it gets changed and the old claim stays visible as a retraction — a discarded hypothesis is worth as much to the next engineer as a confirmed one.
