Integrated capacitive fingerprint module

High-precision fingerprint recognition | Serial communication | Data acquisition window indicator light | Integrated design

Product Features

This product uses a high-performance Cortex core controller and integrates a high-security commercial fingerprint algorithm, supporting functions such as fingerprint enrollment, image acquisition, feature extraction, and fingerprint comparison. No complex fingerprint recognition algorithms are required; secondary development can be performed simply by sending commands via serial port, allowing for rapid integration into various fingerprint recognition applications with high requirements for size and accuracy.

It's easy to use; no knowledge of fingerprint algorithms or internal structures is required. Simple commands are all that's needed to complete the operation.
Built-in commercial algorithms support functions such as fingerprint enrollment, fingerprint comparison, fingerprint image extraction, and fingerprint feature value uploading, offering stable performance and fast recognition speed.
Capacitive fingerprint recognition is highly sensitive; a light touch of the finger on the sensor window is all it takes for rapid recognition.
With high hardware integration, the main controller and fingerprint sensor are integrated into one unit, making it easy to embed into small-sized applications.
Built-in human body sensor with power-off sleep and touch wake-up functions, resulting in lower power consumption.
The fingerprint sensor window features an LED indicator to provide fingerprint scanning guidance.
Onboard UART serial communication interface
It facilitates connection to a PC for communication with a host computer, and also supports embedded hardware platforms such as STM32 and Raspberry Pi.
