Description |
| 1 |
Finger Detection Power + (3.6V – 5V) |
| 2 |
Finger Detection Signal Output (Active High) |

Working Principle:
The module processes fingerprints in two stages: Registration and Matching. During registration, a fingerprint image is captured and stored as a template. During matching, an input fingerprint is compared against stored templates for verification or identification. Results are returned as pass/fail.
Serial Communication:
- Interface: UART (TTL Logic Level)
- Baud Rate: Default 57600bps, configurable (9600 – 115200bps)
- Frame Format: 10 bits (1 start bit, 8 data bits, 1 stop bit), no parity
- Power-Up Delay: Requires ~200ms for initialization after power-on
- RS-232 Compatibility: Requires a level shifter (e.g., MAX232) for PC interface
Applications:
- Access control systems
- Biometric attendance systems
- Security automation
- Embedded authentication devices
- Identity verification terminals
