OVERVIEW
This is a highly integrated round-shaped all-in-one capacitive fingerprint sensor module, which is
nearly as small as a nail plate. The module is controlled via UART commands, easy to use. Its
advantages includes 360° omni-directional verification, fast verification, high stability, and low power
consumption, etc.
Based on a high-performance Cortex processor, combined with high-security commercial
fingerprinting algorithm, the UART Fingerprint Sensor (C) features functionalities like fingerprint
enrolling, image acquisition, feature finding, template generating and storing, fingerprint matching,
and so on. Without any knowledge about the complicate fingerprinting algorithm, all you need to do
is just sending some UART commands, to quickly integrate it into fingerprint verification applications
which require small size and high precision.
FEATURES
⚫
Easy to use by some simple commands, you don't have to know any fingerprint technology, or
the module inter structure
⚫
Commercial fingerprinting algorithm, stable performance, fast verification, supports fingerprint
enrolling, fingerprint matching, collect fingerprint image, and upload fingerprint feature, etc.
⚫
Capacitive sensitive detection, just touch the collecting window lightly for fast verification
⚫
Hardware highly integrated, processor and sensor in one small chip, suit for small size
applications
⚫
Narrow stainless-steel rim, large touching area, supports 360° omni-directional verification
⚫
Embedded human sensor, the processor will enter sleep automatically, and wake up when
touching, lower power consumption
⚫
Onboard UART connector, easy to connect with hardware platforms like STM32 and Raspberry Pi
