R307 Fingerprint Module consists of 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.
Difference Between R305Â and R307 Finger print module:-
Same software protocol as R305 with many improvements
| R305 | R307 | |
| Storage Capacity (Fingerprints) | 250 | 1000 |
| 3.3V Operation | No | Yes |
| USB Operation | No | Yes |
| Finger Detect Output | No | Yes |
R307 is a finger print sensor module with TTL UART interface. The user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person.The FP module can directly interface with 3v3Â Microcontroller. A level converter (like MAX232) is required for interfacing with PC.
The R307 fingerprint module has two interface TTL UART and USB2.0, USB2.0 interface can be connected to the computer; RS232 interface is a TTL level, the default baud rate is 57600 , can be changed, refer to a communication protocol ; can And microcontroller, such as ARM, DSP and other serial devices with a connection, 3.3V 5V microcontroller can be connected directly. Needs to connect the computer level conversion, level conversion note , embodiments such as a MAX232 circuit.
