HLK-FPM383F is a new type of area array semiconductor fingerprint module. Compared with existing products on the market, this module has the advantages ofsmall size, low power consumption, fast recognition speed and high recognition accuracy.
The HLK-FPM383F module is easy to use, and is especially suitable for small, battery-powered devices such as door locks, card readers, and safes; whilemaintaining low power consumption, it can maintain excellent responseperformance and high-speed recognition speed.
This module uses a capacitive fingerprint sensor, which can effectivelydetect fake fingers by measuring fingerprint signals. The surface of the fingerprint sensoruses a high-hardness coating, which can greatly reduce the wear and tear onthefingerprint sensor in daily use. In addition, HLK-FPM383F can withstand15KVstatic electricity, which is not easy to damage the fingerprint sensor when usedinwinter or in areas with high static electricity such as the north.
The HLK-FPM383F module is with a 1.0mm connector, which canbeconnected with ordinary cables to enhance connection reliability.
The HLK-FPM383F interface supports UART, and the default baud rateofUART is 57600. The baud rate can be set by software. (Note: The baud ratewill take effect immediately after the setting is successful. Please use the newbaudratefor communication. If you forget the set baud rate, please return to the factorytoreset or verify all possible set baud rates.)
