This is the user manual for the fingerprint recognition module developed by AraTek Biometrics Technology Co., Ltd. It introduces the features and functions of the module, including fingerprint enrollment, image processing, feature extraction, template generation, template storage, fingerprint matching, etc. The module has a simple and reliable communication protocol and can be embedded into various intelligent products.
The AraTek ARA-EM02 series fingerprint module is a compact, high‑performance biometric sensor that supports enrollment, image processing, feature extraction, template generation, storage, and matching (1:1 and 1:N). It communicates with a host via a standard UART interface, allowing integration into PCs, micro‑controllers, and other devices.
The manual provides hardware pin definitions, UART communication parameters, command packet structures, and detailed performance specifications such as image size, resolution, matching speed, and power consumption. Typical applications include access control, attendance systems, and identity verification. This manual is written in Chinese.

The module uses a standard UART (TTL level) interface with selectable baud rates from 9600 to 115200 bps, 1 start bit, 1 stop bit, and no parity.
Connect GND, VCC (5 V), TXD (serial transmit), RXD (serial receive), PowerEN (power control), and Reset (active‑low) to the host.
The module can store up to 256 fingerprint templates.
Enrollment takes less than 3 seconds per fingerprint.
