R307 Fingerprint Module
An improved compatible version of the R305 Finger Print Sensor Module.
- Storage Capacity (Fingerprints): 1000
- 3.3V Operation: Yes
- USB Operation: Yes
- Finger Detect Output: Yes
The R307 Fingerprint Module consists of an optical fingerprint sensor, high-speed DSP processor, advanced fingerprint alignment algorithm, and high-capacity FLASH chips. It offers improved performance, stability, and simple structure for various functions.
Difference Between R305 and R307 Finger Print Module:
- Same software protocol as R305 with many improvements
R307 is a fingerprint sensor module with a TTL UART interface for storing fingerprint data and configuring it in 1:1 or 1:N mode for identification. It can interface directly with a 3.3V microcontroller, requiring a level converter like MAX232 for PC interfacing.
Pinouts:
- 1: 5V Regulated 5V DC
- 2: GND Common Ground
- 3: TXD Data output - Connect to MCU RX
- 4: RXD Data Input - Connect to MCU TX
- 5: TOUCH Active Low output when there is touch on sensor by finger
- 6: 3.3V Use this wire to give 3.3V to sensor instead of 5V
Features:
- Supply voltage: DC 4.2 ~ 6.0V
- Supply current: Working current: 50mA (typical) Peak current: 80mA
- Fingerprint image input time: <0.3 seconds
- Window area: 14x18 mm
