Item Type: Optical Fingerprint Reader Material: ABS Main Frequency: 120MHz Flash Memory: 1M Bits SRAM: 128KB Fingerprint Collector: Optical acquisition Fingerprint Image Size: 640 x 480(pixel), 508DPI Fingerprint Registration Capacity: 1000 PCS by default Fake Recognition Rate (FAR): < 0.001% Rejection Rate (FRR): < 0.001% Comparison Method:1 : N and 1 : 1 comparison Fingerprint Template Size: 570 bytes Safety Level Setting: Level 1 to Level 5 can be set Factory Setting Value:Level 3 Communication Interface: UART, 3.3V-TTL level or USB communication Serial Communication Parameter Parity None: 1PC Stop Bit Baud Rate: 9600, 19200, 38400, 57600, 115200(BPS) Factory Setting: 115200BPS Operating Voltage DC 3.3V 10% Pin Functions: RST: Reset module, low level is active VIN: Main power supply of fingerprint module, 3.3V by default Power Ground: GND RX: Module receives data pins TX: Module sends data pins Finger Detection Function Circuit Power Supply: 3.3V Wakeup: Finger detection function outputs pin, outputs high level when a finger is pressed on Package List 1 x Optical Fingerprint Reader 1 x USB Cable Professional use, do not understand this knowledge, please choose carefully. 1Process of fingerprint identification, the newly extracted fingerprint feature value is successfully identified and then merged into the fingerprint database, so that the user can use it in the process as better as possible. 2360 automatic correction and recognition, press the correctly registered finger at any angle on the module, the pair is successful, and you can pass. 3The fingerprint recognition rate is low, the maximum is 0.001%, and the false rejection rate (FRR) is less than 0.001%. 4USB model, supports up to 1000 fingerprint users. The fingerprint window adopts waterproof technology. 5Support the full range of windows. Support the secondary development of for Android platform. Communication interface includes UART, 3.3VTTL level or USB communication.
