Features: 1.Multifunction: The all in one fingerprint identification secondary development module that can independently complete fingerprint acquisition, fingerprint registration, fingerprint matching and fingerprint search functions has the advantages of small size, low power consumption, universal interface, high reliability, super easy to use, expandable large capacity 1:N identification, etc., which can be easily embedded into the user system. 2.Self Learning Function: During fingerprint identification, the latest extracted fingerprint feature value will be fused into the fingerprint database after successful identification, so that the user can use it more and more during the process of use. 3.360 Degree Auto Correction Recognition Function: Press the correctly registered finger at any angle on the module, and the comparison can be passed. 4.High Performance: The fingerprint recognition rate is low: the maximum can achieve 0.0001%, that is, in 1,000,000 different fingerprints, randomly pick a fingerprint, and use the other fingerprints in 1,000,000 in turn and the selected fingerprint comparison, there will be a recognition through. Fingerprint rejection rate is low: the maximum can be 0.0001%, in the existing 1,000,000 fingerprints, respectively, using 1,000,000 fingerprints in any order to compare 1,000,000 times, there will be one recognition failure. 5.Wide Application Areas: It can be used in fingerprint access control machine, fingerprint root finder, fingerprint attendance machine, fingerprint locker, fingerprint car one touch start, fingerprint stamp, fingerprint lock, fingerprint safe, fingerprint POS terminal, hospital case fingerprint management, intelligent control equipment, etc. specification:Item Type: Fingerprint Reader Material: ABS CPU: 120MHz Main Frequency, 1M Bits Flash Memory, 128KB SRAM Fingerprint Collector: Optical Collection Fingerprint Image Size: 640x480 PX, 508 DPI Fingerprint Registration Capacity: Default 1000 Pieces, Expandable 5000 Pieces False Acceptance Rate (FAR): < 0.001 % (Security Level 3) Rejection Rate (FRR): < 0.1 % (Security Level 3) Matching Method: (1: N) And (1:1) Matching Fingerprint Template Size: 570 Bytes Security Level Setting: Level 1 To Level 5 Can Be Set, Factory Setting Value: Level 3 Fingerprint Feature Extraction Time: < 0.45 Seconds (1:N) Matching Time (3000 Full Registrations): < 1.5 Seconds Communication Interface: UART, 3.3V TTL Level Serial Communication Parameters: Parity = None, Stop Bit = 1 Flow Control = None Baud Rate: 9600, 19200, 38400, 57600, 115200 (bps) Factory Setting: 115200bps Operating Voltage: for Win Voltage (DC3.3V10%) Operating Current: Less Than 100mA Interface Definition: RST: Make The Module Reset, Low Level Valid (This Pin Needs To Be Used Under Uninterrupted Power Supply To The Module, In Other Cases It Is Recommended To Suspend The Processing) VIN: Fingerprint Module Main Power Supply, Default 3.3V GND: Power Ground RX DP: Module Receive Data Pins TTX DN: Module Send Data Pins +3.3V: Finger Detection Function Circuit Power Supply Wakeup: Finger Detection Function Output Pin, Output High When A Finger Is Pressed On Note: 1. communication process in addition to the FP Cancel instruction, other instructions sent, received must follow the principle of one send and one receive, two instructions sent interval time required greater than or equal to 20ms, less than this time may lead to the later instructions do not respond. 2. From the module Target to Host in the transmission of more than 24byte data, the use of response data packet (Response data packet). 3. Host should not send commands to TARGET when no answer is received. 4. The module indicator does not need to be controlled by default, it will automatically turn on the collector indicator when processing the command, if the correct fingerprint is collected, the indicator will be turned off automatically; if the correct fingerprint is not collected, the collector indicator will be on all the time. You can also use the Sensor LED Control command to turn on or off the collector light according to your needs. 5. The device has password protection mode. After the device password is set, most of the commands cannot be used if the device is not confirmed by the password. If no password is set for the device, all commands can be used without password confirmation. 6. The module automatically enters into initialization when it is powered on, which takes about 300ms. It is recommended to wait for 350ms after powering on the module and then send commands to the module. 7. The module has an automatic finger detection function, that is, when a finger is pressed on the fingerprint collector in low power mode, the Wakeup pin of the module will output a high level. The specific operation is as follows. The +3.3
