BS817
BS817 is a fingerprint sensor array in the BS family — a 208×288 array class at 500+ DPI — sized for lock modules, where the sensor is the most expensive trade-off on the board. One piece is the MOQ; the free SDK and 48h FAE response cover schematic-level pairing on day one.

Array capacitance and optical stack are matched per module design — the FAE team validates your touchpad stack-up within 48h.

One sensor, one dorm floor.
Smart-lock OEMs shipped over 45 M units in 2025, with China holding about 55% of global output — and campus housing is the front edge of that wave. A BS817-based module turns a single dorm door into a managed credential point:
- Floor-level scale-up — controller-side capacity in the 200–1,000 template class covers a residence floor without a second board (family class).
- Rotation without re-enrollment — templates ship between locks through the SDK's 1:1 export format, so room moves cost nothing at the door.
- Programming-safe upgrade — the same BS-series interface family as the module hub, so one firmware branch serves the campus roll.

Where the 70% is made.
Fingerprint chips for lock modules hold about 70% of China's smart-lock segment per domestic industry estimates — this is the sensor line that serves that volume. BS817-family units run through 24h aging flows, burn-in checks and unit-level test pass before packing.
- Volume supply is 10–25 days for orders under 5,000 units; 1 pc ships in 1–3 days for pilots.
- Free SDK covers enrollment, liveness hooks and threshold tuning for FAR/FRR targets.
- Samples carry the 2-year warranty — same terms as production replenishment.

BS817 FAQs
Yes — order 1 pc, and the FAE team will pre-check your module schematic within 48h so the breadboard is right the first time.
The algorithm ships with the sensor-family SDK free of charge, including enrollment and threshold-tuning routines for lock use.
Module-level rating is the −40~85°C family class, with dry-finger handling via capacitance-liveness at the controller; the FAE team sizes your door-side stack-up.
