AllinOne RoundShaped Capacitive Fingerprint Sensor (D) Nail platesized, UART command operation, 360 degree verification Key benefits Compact and easy to integrate: Nail platesized round sensor fits tight spaces and flush panels for a clean, unobtrusive installation. Reliable 360 degree verification: Capacitive sensing captures fingerprints at any rotation so users do not need to align their finger a specific way. Simple serial control: Operates via UART command set for enrollment, verification, and basic template management, reducing hostside development effort. Allinone design: Built to combine sensing and onboard processing to simplify wiring and system architecture. What it does and why you need it Performs fingerprint capture and verification using capacitive sensing technology, enabling secure user authentication in compact products. Solves common integration problems by offering a small physical footprint and standard UART interface that works with most microcontrollers and singleboard computers. Reduces user friction with 360 degree matching so authentication succeeds regardless of finger orientation. Key attributes Form factor: Round, nail platesized sensor designed for limitedspace installations and panel mounting. Operation: Controlled through UART serial commands for enrollment, verification, and control operations. Sensing: Capacitive fingerprint detection optimized for consistent capture across rotations. Integration: Allinone module minimizes external components and simplifies system wiring. Performance: Designed for fast and repeatable verification in embedded applications. Compatibility Works with controllers and host devices that support UART serial communication, including common microcontrollers and embedded controllers. Suitable for firmwaredriven systems that need a small biometric input module with a standard serial protocol. Typical applications Access control panels and door locks where a small, discreet sensor is required for secure user entry. Time and attendance terminals or handheld devices that need compact biometric authentication without complex wiring. Embedded products and IoT devices requiring user authentication with minimal host processing, such as secure kiosks, smart cabinets, and equipment locks. Integration notes Communicate with the module using UART commands for enrollment and verification tasks; refer to the module command reference for exact message formats and workflows. Physical mounting should accommodate the nail platesized round profile for reliable finger placement and repeatable captures. Provide appropriate power supply and serial interface levels according to system host specifications. This sensor is suitable for developers and integrators who need a small, reliable biometric input module with 360 degree verification and straightforward UARTbased control.
