What this page is: the working surface for the 2026-06-29 sample batch. 6 air-pump BP-watch SKUs ordered from 智惠宇 (5) + 豹子 (1) for the pump cycle driver board prototype — rip out the screen, tap the pump driver, run inflate/deflate on a set rhythm. Priority order, crack-first checklist, and what to look for in each.

master checklist — record for each watch when cracked

open questions for after the first 2 are cracked

• Is the pump identical across 智惠宇's lineup? comparing s101 (premium imported) vs P20 (cheapest) tells you if 智惠宇 uses one pump vendor across all their watches or has multiple.
• Does the driver circuit match across molds? if s101 and S26 use the same SOT-23 MOSFET part, you have a single hack point that works across the whole 智惠宇 family.
• Is the 豹子 S17 a different factory's take on the same mold? comparing its internals to the s101 (also square AMOLED) reveals cross-factory BOM sharing.
• Is the TK66 barrel case pump separable from the round case pumps? the barrel case has a totally different cuff geometry — pump subsystem may be a different module entirely.
