Fingerprint Scanner - TTL (GT-521F52) SF_Soft Potentiometers The Sound Detector not only

The Sound Detector not only provides an audio output

* Internal selectable Low Noise Amplifier of 25dB gain nominal

512 of memory can be accessed as tightly coupled memory

you can develop more advanced functions with the DRV2605L driver which improves actuator performance in terms of acceleration consistency

If you only wish to get at the range information a bit sooner and will continue to fire the SRF10 at 65ms of slower
