Fingerprint Access Control Board with R503 Sensor, 120 User Capacity, Biometric Door Lock System Description

K202 Fingerprint Control Board Overview A compact, low power fingerprint control board designed for simple installation and reliable access control. Supports fingerprint registration, adjustable relay output, and a clear reset procedure for quick setup and maintenance. Key features Simple fingerprint registration: Short press SET to enter registration mode. The blue indicator flashes rapidly while registering. Place a finger on the collection area and an audible tone or music plays when registration succeeds. Multiple fingerprints can be registered consecutively in the same session. Finger induction activation: The fingerprint module wakes when it detects a finger, conserving power and improving responsiveness. Storage capacity: Stores up to 120 fingerprint templates. Adjustable relay time: Relay duration is user adjustable by rotating the relay time control. Adjustable range 0.5 to 13 seconds. Power and efficiency: Low power consumption. Operates from DC 10 to 24 V. Compact and easy to install: Small footprint for use inside enclosures or retrofit into existing access control setups. Reset to default: Press SET until a long Di beep and music play to confirm successful initialization. Benefits and problem solving Faster, simpler access management: Eliminates keys and complex PIN management by enabling quick fingerprint enrollment and one touch activation. Flexible control timing: Adjustable relay time allows tailoring the unlock period to different door hardware and user habits. Energy efficient: Finger induction and low power design reduce standby consumption, suitable for battery backed or constrained power systems. Scalable for small installations: With capacity for 120 fingerprints, suitable for small offices, workshops, or gated areas without requiring additional infrastructure. Compatibility and performance Power requirement: DC 10 to 24 V. Relay output: Configurable 0.5 to 13 seconds via the onboard control. Installation: Designed to integrate with common access control circuits and electric locks that accept a relay trigger. Typical applications Small office or workplace door access control for employees and contractors. Storage rooms, equipment cabinets, or supply closets where controlled entry and simple management are needed. Residential or gated entry installations requiring a compact, low power biometric controller. What is included and user notes Control board K202 with fingerprint module and onboard SET control.
