Description
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. Features Integrated STM32 core controller High-resolution capacitive fingerprint sensor with high-accuracy recognition capability Fingerprint capacity of 100 entries Adaptive processing for both dry and wet fingers Fingerprint management, precise matching, and search functions Built-in RGB LED ring supporting seven colors for (working status) indication Development Platform UiFlow2 Arduino IDE PlatformIO Includes 1 x Unit Fingerprint2 1 x HY2.0-4P Grove Cable (20cm) Applications Smart door locks Access control attendance Identity authentication Financial payment Small security systems Specifications Specification Parameter MCU STM32G031G8U6 Fingerprint Module A-K323CP Fingerprint Resolution 508 dpi Image Pixel 80 * 208 Image Acquisition Size 8230 Bytes (80 * 208 / 2 = 8320, 4 bits per pixel) Fingerprint Capacity 100 entries Fingerprint Data Size 7262 Bytes / entry Communication Method UART 115200bps @ 8N1 Power Consumption Working mode: Breathing light ON 40mA; Breathing light OFF 37.25mA Sleep mode: 14.11mA Product Size 24.
