    Product description

    SF201 application capacitance sensing technology, and the surface coating to enhance hardness and antistatic ability.

    Built-in class a digital converter can be read directly by using the SPI interface MCU to converted the fingerprint image data, no need to plus any circuit.

    Fingerprint image by pixel array induction through the signal amplifier, a/d converter, and subsequent digital processing in order to obtain clear fingerprint images.Ratio by adjusting amplifier and a/d converter reference voltage, can do adjustment according to image quality, to adapt to the different characteristics of dry wet finger.

    In addition, within the working frequency and SPI interface frequency can be adjusted according to the requirements to do.
