Introduction:

This is a highly integrated circular integrated capacitive fingerprint module, the size of the fingernail, the serial command operation, supports 360-degree rotation recognition, and has the advantages of fast recognition, strong stability and low power consumption.

The main control of the high-performance Cortex core is integrated with a high-security commercial fingerprint algorithm, which supports functions such as fingerprint entry, image acquisition, feature value extraction, template generation, template storage, and fingerprint comparison.

You don't need to understand the complex fingerprint recognition algorithm, you only need to send commands through the serial port for secondary development, which can quickly integrate me into various fingerprint recognition applications that require high volume and accuracy.

Characteristic:

Easy to use, no need to understand the fingerprint algorithm and internal structure, only a simple command can complete the corresponding operation

Built-in commercial algorithm, support fingerprint input, fingerprint comparison, extract fingerprint image and upload fingerprint feature value, etc., stable performance, fast recognition speed

Capacitive fingerprint recognition, sensitive sensing, as long as your finger gently touches the collection window, it can be quickly recognized

High degree of hardware integration, the main control and fingerprint sensor are integrated, which can be easily embedded into various small volume applications

Stainless steel rigid narrow round structure, large fingerprint sensor contact area, support 360 degree rotation identification

Built-in human induction device, with power-down sleep and touch wake-up function, lower power consumption

Onboard UART interface for easy access to hardware platforms such as STM32 and Raspberry Pi
