FPM10A Fingerprint Sensor Module for Arduino, 3.3V 5V Optical Reader with Fast Biometric Access

FPM10A Optical Fingerprint Reader Sensor Module Overview and key benefits Compact, readytointegrate fingerprint sensor for secure biometric identification. Fast capture and matching: fingerprint image and search times under 1.0 second for quick user verification. Low power and easy integration: works with 3.3 V or 3.6 to 6.0 V supply and communicates via UART (TTL) or USB for use with common microcontroller platforms. Reliable accuracy at security level 3: very low false accept rate and low false reject rate for practical access control applications. What this module does for you Replaces PINs and keys with fingerprint authentication to simplify access and improve convenience. Fits into embedded systems, electronic locks, attendance terminals, and custom control panels without major redesign. Stores up to 200 fingerprint templates locally for ondevice verification, reducing external processing and network dependencies. Technical highlights Model: FPM10A fingerprint reader sensor module Supply voltage: DC 3.6 to 6.0 V or 3.3 V Supply current: < 120 mA; peak current < 140 mA Fingerprint image time: < 1.0 second Optical window size: 14 x 18 mm Matching mode: 1 : 1 Search mode: 1 : N Signature file size: 256 bytes Template file size: 512 bytes Storage capacity: maximum 200 templates Security level: Five (levels 1 to 5) False accept rate (FAR): < 0.001% at security level 3 False reject rate (FRR): < 1.0% at security level 3 Search time: < 1.0 second (1:500, mean) PC interface: UART (TTL logic level) or USB 2.0 / USB 1.1 Communication baud rate (UART): 9600 x N bps, N = 1 to 12; default N = 6 (57600 bps) Working environment: temperature 20 C to 50 C; relative humidity 40% to 85% RH (noncondensing) Storage environment: temperature 40 C to 85 C; relative humidity < 85% (noncondensing) Dimensions: sensor module 56 x 20 x 21.5 mm Integration and wiring notes Serial communication interface designed for use with 3.3 V or 5 V microcontrollers. Connect module transmit pin (TD) to host RXD, and module receive pin (RD) to host TXD. For RS232 level host devices (for example a PC), use a level conversion circuit such as MAX232 between the module and the host to convert TTL to RS232 levels. Supports direct USB connection using USB 2.0 / USB 1.1 where applicable. Included in package 1 x FPM10A optical fingerprint reader sensor module Practical applications Electronic door and cabinet locks: mechanical keys with fingerprint access on cabinets, lockers, and doors. Access control for small offices and labs: local storage of user templates allows ondevice authentication without continuous network access. Time and attendance terminals: fast capture and reliable matching for tracking employee checkin and checkout. Why choose this module Proven optical sensing and template storage designed for embedded integration. Compact form factor and standard serial or USB interfaces reduce development time. Clear specification of power, timing, and environmental limits helps ensure reliable installation in a variety of settings. Notes Ensure proper voltage levels and level shifting when connecting to RS232 hosts. Follow recommended environmental ranges for reliable longterm operation.
