R307-S fingerprint module is composed of optical fingerprint sensor, high-speed DSP processor, high-performance fingerprint comparison algorithm, high-capacity FLASH chip and other software and hardware. It has stable performance, simple structure, fingerprint input, image processing, fingerprint comparison, search, template storage and other functions. It uses dark background to collect fingerprints, and the light color is blue.

Product features:

Complete functions: independently complete fingerprint collection, fingerprint registration, fingerprint comparison (1:1) and fingerprint search (1: N) functions.  

Small size: The product is small in size, without a circuit board connected with an external algorithm DSP chip, and has been integrated into one, which is convenient for installation and has few failures.  

Ultra low power consumption: the overall power consumption of the product is extremely low, which is suitable for occasions requiring low power consumption.   

Strong anti-static capability: It has a strong anti-static capability, and the anti-static index is above 15KV.  

Simple application development: developers can develop fingerprint application products by themselves according to the control instructions provided, without professional fingerprint identification knowledge, and are suitable for fingerprint locks, fingerprint safes and other occasions.

Adjustable security level: applicable to different applications. The security level can be set and adjusted by the user.

Finger touch inductive signal output, low level is effective, and the standby current of inductive circuit is extremely low, lower than 5uA

Brief description of R307-S fingerprint module:

1. Fingerprint capacity:

The storage capacity of R307S fingerprint module is 300 pieces and 1000 pieces, with two capacities in total

2. Interface description:

The fingerprint module has RS232 and USB2.0 at the same time, and the dual interface communicates with the outside world; USB 2.0 interface can be connected to the computer; RS232 interface is TTL level, and the default baud rate is 57600, which can be changed. Please refer to the communication protocol; It can be connected with SCM, such as ARM, DSP and other devices with serial ports, and 3.3V 5V SCM can be directly connected. Level conversion is required when connecting the computer. Please pay attention to level conversion, such as MAX232 circuit.  

3. About the power supply of the module

If two contacts marked with 3.3V on the circuit board of the fingerprint module are short circuited, DC3.3V can be used.
