Product Name: Grow R502-a Small Circular Ring LED Fingerprint Module Model NO.: R502-A Fingerprint Capacity: 200 Communication Interface: RS232 Screen: as Picture Color: as Picture Clock: Without Clock Voice Service: Without Voice Service Voltage: DC 3.3V Effective Collection Area: Diameter 15.5 (mm) Sensing Array: 190*190 Pixel Resolution: 508 Dpi Abrasive Resistance Intensity: 1 Million Times Antistatic Capacity: 15kv Fingerprint Module External Diameter: 22mm Fingerprint Module Inner Diameter: 19.5mm Fingerprint Module Height: 5mm Weight: 5g LED Control: Yes Trademark: GROW Transport Package: Standard Export Carton Package Specification: Diameter 22 (mm) Origin: China HS Code: 8471609000 Product Description Description 1. Integrated image collecting and algorithm chip together, ALL-in-One 2. The flexibility to adapt to the conditions was the fingers, whether it is dry fingers, wet fingers, light texture fingerprints fingers, and old fingers, all have high recognition rate 3. The main application areas: can be embedded into a variety of end products, such as: access control, attendance, safety deposit boxThe R502-A has circular ring indicator light that can be controlled by command.***The different between R502-A with R503:R502-A is thinner and samller, others are same.If you think R503 is too big, you can chose R502-A.***The different between R502-A with R502:We changed the R502's LED to Circular Ring LED.If you need small and thin module, but need circluar ring LED, you can chose R502-A..R502-ASpecificationsModelR502-ATypeCapacitive Fingerprint ModuleInterfaceUART(TTL)Resolution508 DPIVoltageDC 3.3VFingerprint Capacity200Sensing array192*192 pixelWorking current20mAStandby currentTypical touch standby voltage: 3.3V, Average current: 2uAFingerprint module external sizeDiameter 22 (mm)Fingerprint module inner sizeDiameter 19.5 (mm)Fingerprint module height5 (mm)Effective collection areaDiameter 15.5 (mm)ConnectorMX1.0-6PinLED ControlYESLED ColorPurple and Blue and RedScanning Speed< 0.2 secondVerification Speed< 0.3 secondMatching Method1:1; 1:NFRR≤1%FAR≤0.001%Work environment-20C ---60CWork Humidity10-85%Anti-static capacity15KVAbrasive resistance intensity1 million timesCommunications baud rate (UART):(9600 × N) bps where N = 1 ~ 12(default N = 6, ie 57600bps)Files·ProvideFree Reference SDK Files for Arduino, Android,.Net,Windows and so on.·Provide User ManualYou can download the R502-A user manual from this website link:https://www.dropbox.com/sh/epucei8lmoz7xpp/AAAmon04b1DiSOeh1q4nAhzAa?dl=0R502-A Operation display video on Youtube:https://youtu.be/8w_bkgwTabEIf need SDK files,pls contact us.
