Description
Features:
Perfect function: independent fingerprint collection, fingerprint registration,
fingerprint comparison (1: 1) and fingerprint search (1: N) function.
Small size: small size, no external DSP chip algorithm, has been integrated, easy to install, less fault.
Ultra-low power consumption: low power consumption of the product as a whole, suitable for low-power
requirements of the occasion.
Anti-static ability: a strong anti-static ability, anti-static index reached 15KV above.
Application development is simple: developers can provide control instructions, self-fingerprint application product development, without the need for professional knowledge of fingerprinting.
Adjustable security level: suitable for different applications, security levels can be set by the user to adjust.
Finger touch sensing signal output, low effective, sensing circuit standby current is very low, less than 5uA.
Interface Description:
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.
