TTC
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 prom
