Easy development: serial port UART operation (directly connect to any single-chip microcomputer with serial port), extremely simple operation.Standard 16-pin universal interface: sensors can be independently selected and replaced by optical and other sensors commercial algorithms are used.“Scientific structure”: the module adopts a modular structure, fingerprint sensor + processing motherboard + algorithm platform.Speed & stability are better than Chinese chips. Stability first: the module adopts STM32F205 MCU with low power consumption and fast speed.Sensitive fingerprint sensing and fast identification speed: the fingerprint module adopts high-precision optical path and imaging components, so only hands are needed when using it.It exposes a UART interface to be driven from a host microcontroller or processor. It supports fingerprint entry, image processing, feature value extraction, template generation, template storage, fingerprint comparison, and search. The UART fingerprint reader module is powered by STM32F205 high-speed digital processor from STMicro and integrates a fingerprint algorithm (TFS-9), as well as a high-precision optical sensor (TFS-d400). 3 hardware componentsĪ total of three hardware modules are used:įingerprint identification module with UART-TTL The specific model of this display is STONE STVC050WT-01, which communicates with MCU through UART, and will be covered in later chapters. But I want to use an LCD display, so I chose a 480×272 resolution serial LCD display. The demo program of the fingerprint module uses LED lights to prompt the user to enter the fingerprint and compare the status (success or failure). Since the fingerprint module manufacturer provides a demo program for STM32F103 series microcontrollers, I bought a small development board based on STM32F103C8T6. It supports fingerprint scanning, fingerprint entry, fingerprint comparison, and fingerprint deletion. This fingerprint module can be easily purchased online, connected over UART to an MCU board. However, I thought that since the fingerprint identification module had been purchased, I would simply test it.
When I selected the fingerprint identification module, the project was suspended. This month, I planned to develop a fingerprint door lock project. CNXSoft: This is a guest post by Amy working for STONE Technology, a company specializing in industrial liquid crystal display modules
