Waveshare Square Integrated Capacitive Fingerprint Development Module Cortex Core UART Serial Communication Sensor 192192
Feature:
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 entry, fingerprint comparison, extract fingerprint image and upload fingerprint feature value and other functions, stable performance and fast recognition speed
Capacitive fingerprint recognition, sensitive sensing, as long as the finger gently touches the collection window to quickly recognize
High degree of hardware integration, the main control and fingerprint sensor are integrated, which can be easily embedded into various small volume applications
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
