R307 Capacitive Fingerprint Reader/Module/Sensor/Scanner Optical Fingerprint Sensor

Key Features:

Fingerprint Capacity: Stores up to 1000 fingerprints.

Interfaces:

● Dual interfaces: RS232 (TTL level, default baud rate 57600, adjustable) and USB2.0.

USB2.0 connects to PCs.

RS232 interfaces directly with microcontrollers (e.g., ARM, DSP) supporting 3.3V/5V logic.

Note: PC connection requires level conversion (e.g., MAX232 circuit).

Module Self-Test:

● Power-on: Flash from the fingerprint window indicates normal self-check.

No flash? Check power supply connections.

Normal operation may cause slight chip heating (tested for safety).

● Colour:Black
