FPM10A Optical Fingerprint Reader Sensor Module with Serial Communication Interface Overview The FPM10A is an optical fingerprint sensor module designed for integration into electronic locks and access control systems. It captures fingerprint images and transmits data over a standard serial interface for easy connection to host controllers and embedded systems. Key benefits Simplifies secure access: Replaces mechanical keys and numeric codes with fingerprintbased entry to reduce key management and unauthorized access. Easy to integrate: Standard serial communication makes the module straightforward to connect to microcontrollers, singleboard computers, and access controllers that accept serial data. Compact and adaptable: Small module footprint fits into lock housings, control panels, and compact enclosures for retrofit or designs. Reliable optical sensing: The optical sensor provides clear fingerprint capture for template enrollment and verification workflows handled by the host system. Flexible deployment: Designed to work with a variety of lock actuators and control electronics, enabling rapid prototyping and production use. Important attributes Function: Optical fingerprint capture for authentication and access control; sends image or template data via serial interface for host processing. Interface: Serial communication suitable for UARTlevel connections to controllers and processors. Compatibility: Integrates with control boards and systems that support serial input and processing of fingerprint data. Compatible with common embedded development workflows. Size and form factor: Compact, boardlevel module intended for embedded and enclosuremounted installations. Construction and materials: Sensor uses an optical capture surface integrated on a compact PCB module designed for mounting within access devices. Performance considerations: Intended for responsive fingerprint capture and reliable data transfer over serial links when paired with a capable host processor. Practical applications Electronic door locks: Install in residential or commercial lock assemblies to add fingerprint entry and centralized control. Access control panels: Integrate into standalone or networked controllers to authenticate personnel for restricted areas. Equipment and cabinet security: Add biometric entry to tool cabinets, server racks, safes, or kiosks to limit access to authorized users. Integration tips Connect the module to a host controller using the serial interface and implement enrollment and verification routines on the host. Allow for a clear mounting position and user access to the sensor surface for reliable fingerprint capture. Ensure the host device can manage template storage, matching, and user administration if those functions are required. The FPM10A optical fingerprint sensor module provides a practical, compact option for adding biometric authentication to locks and access systems using a straightforward serial interface for integration into embedded and control projects.
