GROW KR501 Fingerprint Control Board with Fingerprint Module High Level Output Operation Video

This is KR501 operation video.

Technical parameter：
Fingerprint Capacity: 20
Working Voltage: DC 3.7-10V
Standby Current (excluding external equipment):2.5-7uA, typical value: 3uA
Working Current (excluding external equipment): 40-250mA: typical value: 45mA
Output: 1 second, 3.3V-500mA
Low voltage alarm: ≤4.8V

Instructions for control board：
After the fingerprint is passed, the OUT1 pin outputs a signal with a voltage of 3.3V and a current of 500ma for 1 second. In the initialization state, any fingerprint can pass through.

1. Register Fingerprint: Long press the registered fingerprint(In initial state press any fingerprint), until the blue indicator light turn on and hearing music, means the system in register state, press the finger with multiple times in fingerprint collection area,each press have “di” sound, until hearing music means fingerprint register successful. Fingerprint can be registered continuously when system in register state; if no need adding fingerprint more, waiting a few seconds.
Note: In the initialization state,must have to register more than 2 correct fingerprints for the first time,then the system can be removed from the initialization state.

2. Delete Fingerprint(Back to initialization state):
2.1 Long press the registered fingerprint, until the red indicator light turn on,means all fingerprints are deleted and back to initialization state.
2.2 Use INIT_KEY pin. In the standby state, make the INIT_KEY pin ground connection, until the red indicator to turn on, hear the “Di-” sound, disconnect the grounding, the indicator turns green, means all fingerprints are deleted and back to initialization state.
