Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> The Waveshare UART Fingerprint Reader uses an STM32F205 processor with an optical sensor and a commercial fingerprinting algorithm. Communication is via the UART interface at a default baud rate of 19200.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/8552 8552 – UART Fingerprint Reader]<br /> * [https://shop.jw-tech.eu/p/WSAL8552 WSAL8552 – UART Fingerprint Reader]<br /> <br /> == Technical overview ==<br /> * Processor used: STM32F205, dedicated to running the commercial algorithm and not available for secondary development.<br /> * Sensor type: Optical fingerprint sensor.<br /> * Interface: UART; default baud rate 19200.<br /> * Serial communication requires a common-ground connection between the module and the PC.<br /> * The MINI USB port is only for firmware updates and must remain disconnected during normal operation.<br /> * The BL pin controls the backlight; the module can manage it automatically, so the pin usually stays unconnected.<br /> * When capturing images on a host computer, set the baud rate to 9600.<br /> * Power consumption: dynamic approx. 18 mA, static 0 mA.<br /> <br /> == Notes and version constraints ==<br /> * No specific commands or protocol values are provided in the source; a command list must be derived separately from the user manual.<br /> * Exact firmware version and related compatibility limits are not specified.<br /> * For connecting to a PC, using a matching Waveshare USB-to-UART module is recommended; selection depends on your setup.<br /> * For errors such as &#039;mscom32.ocx&#039;, files must be copied to specific Windows folders depending on OS architecture and registered as administrator – each step requires manual verification.<br /> * If new fingerprints are not recognized, the &#039;upload eigenvalue&#039; option must be disabled, otherwise the values are stored only on the PC and not written into the module.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/UART_Fingerprint_Reader UART Fingerprint Reader - Waveshare Wiki]<br /> * Source revision: 69177<br /> * Captured: 2026-08-29T09:18:17+00:00<br /> * SHA-256: &lt;code&gt;4df03a1ce692e02a3f9ed5b5f24b83a8fe17c1930b63996e847ae443498f6702&lt;/code&gt;</div>
