HLK-FPM093D is a new type of face-array semiconductor fingerprint module, which has the advantages of small size, low power consumption, fast recognition

speed, high recognition accuracy and so on, compared with the existing products in the market.

The HLK-FPM093D module is easy to use and is especially suitable for applications in smaller, battery-powered devices such as door locks, card readers, and safes, 

where low power consumption maintains excellent responsiveness and high recognition speed.

This module adopts capacitive fingerprint sensor, which can effectively detect the problem of fake finger by measuring the fingerprint signal. The surface of the

fingerprint sensor uses a high hardness coating, which can greatly reduce the wear and tear on the fingerprint sensor in daily use. In addition, HLK-FPM093D can

withstand 15KV static electricity, which is not easy to damage the fingerprint sensor when used in winter or in the north and other areas where static electricity

is relatively high.

The HLK-FPM093D module uses a 1.0mm connector that can be connected using ordinary cables for enhanced connection reliability.

HLK-FPM093D interface supports UART, the default baud rate of UART is 57600. you can set the baud rate by software. (Note: The baud rate takes effect

immediately after it is set successfully, please use the new baud rate to communicate. If you forget the set baud rate, please return to the factory to reset or

verify all baud rates that may have been set.)
