Adopting LGA package, it supports 360° arbitrary direction recognition with 508DPI resolution. High signal-to-noise ratio, low power consumption, fast response, ultra-low rejection rate and false recognition rate, can be applied to smart door locks, safes, POS machines and identity authentication systems. Product Parameters Module size: φ21mm Recording times: 3/8 times Resolution: 108/108pixel Resolution: 508DPI Interface protocol: TTL serial port Communication Baud Rate: Default Baud Rate 57600bps/1 Start Bit/1 Stop Bit 3.3VTTL level Interface and wire sequence: 1.0mm / 6Pin horizontal paste Fingerprint library capacity: 100 Storage temperature and humidity: -40/125/; 45/95/RH Operating temperature and humidity: -40/85/; 45/85/RH False recognition rate: <0.001/ Rejection rate：<=5/ Comparison mode: 1:N Standby current(sensor)/luA Operating current (algorithm MCU): /14mA ESD level: non-contact discharge /15KV / contact discharge /8KV ZW3020: Product Introduction ZW3020 series modules are upgraded with three core features: Firstly, it adopts optimized image acquisition and pre-processing driver, which effectively shortens the time consuming image acquisition and pre-processing; secondly, it improves the image quality and response speed after initialization. The first is the adoption of optimized image acquisition and pre-processing driver, which effectively shortens the time consuming image acquisition and pre-processing, and improves the image quality and response speed. Secondly, after initialization, it automatically sends 0x55 bytes handshake logo, which accurately feedbacks the module readiness status and ensures the smooth flow of receiving commands from the host computer; Third, the new “AutoSearch” command function allows users to complete the search operation with a single command, simplifying the interaction process and enhancing the ease of use. This simplifies the interaction process and enhances the convenience of use.
