Precision Capacitive Fingerprint Reader (B) Module A compact capacitive fingerprint module designed for reliable biometric enrollment, image processing, matching and searching. Dual communication ports provide flexible integration with microcontrollers and host systems while onmodule processing reduces host workload. Key benefits Accurate biometric recognition using a precision capacitive sensing surface for consistent fingerprint capture. Flexible integration via dual ports UART and USB for direct connection to microcontrollers, single board computers and PCs. Onmodule fingerprint enrolling, image processing, matching and searching to simplify development and speed response times. Reduces system design complexity by handling core biometric operations on the module rather than requiring heavy host processing. Suitable for embedded projects and standalone devices where compact, reliable fingerprint authentication is required. Main features Functionality: fingerprint enrolling, image processing, fingerprint matching and fingerprint searching handled by the module. Interfaces: dual ports UART and USB for versatile connectivity options and straightforward data exchange. Sensor type: capacitive fingerprint sensor for precision image capture. Form factor: module format suitable for integration into embedded systems and terminals. Performance: designed to deliver consistent recognition performance across repeated use and typical environmental conditions. Practical applications Access control panels and door locks: add biometric entry to secure rooms or cabinets with local enrollment and matching handled on the module. Time and attendance terminals: capture and verify employee fingerprints onsite without overloading the main controller. Embedded authentication for kiosks and payment terminals: use the module to verify users before allowing transactions or system access. Integration notes Use the UART or USB port to connect the module to your controller or host system. The module performs enrollment, image processing and matching tasks to minimize host processing requirements. Suitable for projects that need a compact biometric interface with reliable fingerprint capture and local matching capabilities.
