SFM-V1.7 Semiconductor Integrated UART Fingerprint Sensor in Sensors

Description

Description

The SFM-V1.7 integrated semiconductor fingerprint module integrates a color surround light strip, which is mainly composed of an integrated fingerprint sensor and fingerprint algorithm. Realize fingerprint registration, comparison and deletion functions. The module has an exquisite, thin and integrated appearance, has a ring-shaped cool breathing light, fast fingerprint recognition, high security, supports 360-degree recognition at any angle, deep self-learning function, high performance and low power consumption. The module uses standard UART communication. Can provide customers with efficient and flexible secondary development support. At the same time, the integrated chip greatly reduces the size of the fingerprint module. The product structure is simple and modular design improves the stability and consistency of the product.

The SFM-V1.7 semiconductor fingerprint module application provides a usable external control part through the serial port to communicate with each other in accordance with the SFM-V1.7 integrated program communication protocol to realize a fingerprint processing module function platform. Convenient for secondary development. It is widely used in fingerprint door locks, drawer locks, fingerprint collectors, identification, authorization and embedded biological touch.

Communications baud rate (UART):
(9600 × N) bps where N = 1 ~ 12(default N = 6, ie 57600bps)

Feature:

  • Working current: the current when the fingerprint module is in the imaging state, such as the registration process and comparison process
  • Static power consumption: the current when the fingerprint power supply voltage of the fingerprint module is 0 level and the touch power supply voltage is 3.3V; if the touch power supply voltage exceeds the specified range, abnormalities may occur
  • Communication interface: standard UART TTL level
  • Baud rate: default 115200 bps, 1 start bit, 1 stop bit, 3.3V TTL level
  • Connector: XH-6-1.0, 6-Pin wire harness vertical strip connector, spacing 1.0mm
