Pro Mini 3.3V/8M 5V/16M ATMEGA328 ATMEGA328P-AU For Arduino

1. Integrated image collection and chip algorithm together, each 2. The flexibility to adapt to the conditions was fingers, whether it is dry fingers, wet fingers, light textured fingerprints fingers, and old fingers, all have a high recognition rate 3. Application of the main areas: Can be embedded into a variety of end products, such as: access control, attendance, safe 4. The R503 fingerprint module has a built-in chip algorithm 5. The interface line spacing is 1.0mm, and the line length is 20cm. Wire diameter is 25mm, easy to install. Power supply: DC 3.3V Working current: 30mA (typ.) Peak current: 40mA Fingerprint image entry time: less than 0.3 seconds Acquisition window area: 15mm Image pixel diameter: 192*192 pixel Image resolution: 508dpi Adjust method: Comparison method (1:1) Search method (1:N) Storage capacity: 200 pieces Security level: five (from low to high: 1, 2, 3, 4, 5) False detection rate (FAR): less than 0.0001% authentic rejection rate ( FRR): less than 1.0% Search time: less than 0.3 seconds (1:1000, average) Host computer interface: RS232 (TTL logic level, 3.3V) Communication baud rate: (9600xN)bps when N = 1 ~ 12 (choice Default value N = 6, that is 57600bps) Working environment: Temperature: -20 Celsius-+ 45 Celsius Relative humidity: 10% RH-85 % relative humidity (no condensation) Color: Silver Material: Plastic + Metal Size: Fingerprint Height module : 15mm Package Contents: 1 x Barcode Scanner Module Only the above package content, other products are not included. Note: Different shooting light displays may cause the color of the item in the picture a little different from the real thing. The measurement gives up +/- 1-3cm.
