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: 14×18 mm
