This section details the physical connection and initial setup of the FM225 module.

5.1 ແຜນວາດ Pinout

Refer to the diagram below for the pin assignments for both UART and USB interfaces.

5.2 ການເຊື່ອມຕໍ່ໂມດູນ

1. ການເຊື່ອມຕໍ່ພະລັງງານ: Connect the module to a stable DC power supply within the range of 5.5V to 9V at 1A. Ensure correct polarity.
2. ການໂຕ້ຕອບການສື່ສານ:
   • UART: Use the provided connection wires to interface with your host system via UART. Refer to the pinout diagram for TX/RX and GND connections.
   • USB: Connect the module to your host system using the provided USB cable. This interface is typically used for data transfer and configuration.
3. ການຕິດຕັ້ງ: Securely mount the module in its intended location, ensuring the camera lenses have a clear, unobstructed view of the area where facial recognition will occur. Consider the optimal recognition distance (0.3m to 1.1m) and height (1.35m to 2.20m).

6. ຄໍາແນະນໍາການດໍາເນີນງານ

The FM225 module operates primarily through commands sent via its communication interfaces. Specific software or SDKs provided by the manufacturer are typically required for full functionality, including face enrollment and recognition.

6.1 Face Enrollment

To enroll a new face into the module's memory:

1. Ensure the module is powered on and connected to your host system.
2. Use the manufacturer's provided software or send the appropriate UART/USB commands to initiate the enrollment process.
3. Position the subject's face within the recognition distance (0.3m to 1.1m) and within the recognition angle (supports multi-angle input).
4. Follow the on-screen prompts or command responses to complete the enrollment. The module can store up to 100 facial features.

6.2 ການຮັບຮູ້ໃບໜ້າ

Once faces are enrolled, the module can perform recognition:

1. The module continuously scans for faces within its field of view.
2. When a face is detected, the module compares it against its stored facial features.
3. If a match is found with sufficient accuracy (98.85%), the module will output a recognition result via the chosen communication interface.
4. The module's live detection feature helps prevent recognition from photos or videos.

7. ບໍາລຸງຮັກສາ

The FM225 module requires minimal maintenance to ensure optimal performance.

• ທໍາຄວາມສະອາດ: Gently wipe the camera lenses with a soft, lint-free cloth. Do not use abrasive cleaners or solvents.
