R307 Fingerprint Module (upgraded version of R305)

R307 fingerprint module consists of an optical fingerprint sensor, high-speed DSP processor, high-performance fingerprint alignment algorithm, high-capacity FLASH chips and other hardware and software composition, stable performance, simple structure, with fingerprint entry, image processing, fingerprint matching, search and template storage and other functions.

R307 uses Same software protocol as R305 with many improvements

Difference Between R305 (Old) and R307 (New)

	R305	R307
Storage Capacity (Fingerprints)	250	1000
3.3V Operation	No	Yes
USB Operation	No	Yes
Finger Detect Output	No	Yes

The R307 has two interface TTL UART and USB2.0, USB2.0 interface can be connected to the computer;
