Item Type: Capacitive Fingerprint ModuleMaterial: PVCCPU: 144MHz Main Frequency, 1M Bits Flash Memory, 128KB SRAMFingerprint Collector: Capacitive Collector 192x192 (pixel) 508DPIFingerprint Registration Capacity: 1000 Pieces by DefaultFalse Recognition Rate (FAR): 0.001 % (Security Level 3)Rejection Rate (FRR): 0.1 % (Security Level 3)Matching Method: (1:N) and (1:1) MatchingFingerprint Template Size: 570 Bytes ByteSecurity Level Setting: Level 1 to Level 5 Can Be Set, Factory Setting Value: Level 3Fingerprint Feature Extraction Time: 0.45 Seconds(1:N) Matching Time (3000 full registrations): 1.5 SecondsCommunication Interface: UART, 3.3V-TTL LevelSerial Communication Parameters:No Parity Parity = NONE, 1 Stop Bit Stop Bit = 1No Flowing Control = NONEBaud Rate is 9600, 19200, 38400, 57600, 115200 (bps)Factory Setting: 115200bpsOperating Voltage: Win Voltage (DC3.3V10%)Operating Current: Less Than 100mAInterface 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 3.3VGND: Power GroundRX/DP: Module Receive Data PinsTX/DN: Module Send Data Pins+3.3V: Finger Detection Function Circuit Power SupplyWakeup:Finger Detection Function Output Pin, Output High when a Finger is Pressed OnStyle7. 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 FollowsThe +3.3V of The Module Should Be Kept Powered All the Time and Cannot Be Disconnected. When Low Power Consumption is Needed, Disconnect the VIN Power Supply, then when a Finger Touches the Fingerprint Collector Glass, the WKP Pin of the Module Will Output High Level, Take It Away and Turn Back to Low LevelAfter WKP Output High Level is Detected, when the Fingerprint Module Needs to Work, Turn on the VIN Power And Wait for 350ms and then Send the Command to the Module .wang-edit-text{ font-family:Arial important; } .wang-edit-text table { border-top: 1px solid 000; border-left: 1px solid 000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid 000; border-right: 1px solid 000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; } 1Secondary Development Module: Capacitive fingerprint module can independently complete the fingerprint collection, registration, and search function of the secondary development module fingerprint identification 2Practical Functions: Capacitive fingerprint reader with small size, low power consumption, universal interface, high reliability, super easy to use, expandable large capacity 1:N identification 3Self Learning Function: During fingerprint recognition, the latest extracted fingerprint feature value will be fused into the fingerprint database after successful recognition 4360 Degree Auto Correction: Press the correctly registered finger at any angle on the module, and the comparison can be passed 5Low Recognition Rate: The maximum can achieve 0.0001%, that is, in 1 million different fingerprints, randomly pick a fingerprint, and use the other fingerprints in 1 million in turn and the selected fingerprint comparison, there will be a recognition through 6Scope of Application: Can be used in fingerprint access control machine, fingerprint attendance machine, fingerprint locker, fingerprint car one key start, fingerprint lock, fingerprint POS terminal, intelligent control equipment, etc
