Unit Fingerprint2

SKU:U203

Description

The Unit Fingerprint2 is a high-performance fingerprint recognition sensor unit, internally integrating an STM32 core controller and an A-K323CP all-in-one fingerprint recognition module. It uses a semiconductor capacitive sensor with functions such as fingerprint acquisition, feature extraction, registration, comparison, storage, and retrieval. The module has a built-in fingerprint recognition algorithm capable of adapting to both dry and wet fingers. It offers flexible fingerprint data management, high data security, and fast search and positioning functions. This unit adopts a UART communication interface for easy integration with various main control platforms and includes a multicolor LED ring and power indicator for interactive status prompts. It is ideal for rapid development and integration in scenarios such as smart door locks, access control attendance, identity authentication, financial payment, and small security systems.
