Grow KR501 Fingerprint Control Board - 20 Fingerprint Capacity, 3.7-10V DC
The Grow KR501 Fingerprint Control Board is a compact biometric module designed for secure access control systems, operating from a wide 3.7-10V DC supply and compatible with 3.3V logic microcontrollers like Arduino, ESP32, and Raspberry Pi.
Features
- Stores up to 20 unique fingerprints for multi-user access control.
- Wide operating voltage range from 3.7V to 10V DC for flexible power supply integration.
- Ultra-low standby current of 2.5-7 µA ensures minimal power consumption in idle state.
- Provides a 1-second, 3.3V/500mA high-level output signal to directly drive relays or solenoids.
- Compact 36mm diameter circular PCB design for easy integration into panels and enclosures.
