Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> The capacitive fingerprint reader uses an STM32F105R8 processor and a commercial recognition algorithm over UART. The source does not provide complete pin or command details.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL13694 WSAL13694 – Capacitive Fingerprint Reader]<br /> <br /> == Technical overview ==<br /> * Onboard processor: STM32F105R8<br /> * Interface: UART<br /> * The source calls the device a capacitive sensor but also mentions “optical sensor” in the title; the exact sensing technology is unclear.<br /> * A WAKE pin signals finger contact by outputting a high-level signal.<br /> * When the finger is released, the WAKE pin returns to low level.<br /> * The wake-up function operates only when the RST pin is held low and the module is in sleep mode.<br /> * No 3D CAD/STEP file is available according to the source; only 2D images are provided.<br /> * Technical support is available on weekdays from 9 AM to 6 PM GMT+8.<br /> <br /> == Notes and version constraints ==<br /> * The source provides no specific UART commands, voltage, or current values.<br /> * The combination of “capacitive” and “optical” in the description is contradictory and needs clarification.<br /> * The absence of a 3D CAD file may cause issues during mechanical integration.<br /> * No information on compatibility, certifications, warranty, or safety is present.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/Capacitive_Fingerprint_Reader Capacitive Fingerprint Reader - Waveshare Wiki]<br /> * Source revision: 81852<br /> * Captured: 2026-08-30T03:55:31+00:00<br /> * SHA-256: &lt;code&gt;c4ec5be38c1e50dc980ee0446fe83682c66a144d6407886d1f02df5bdb9d31df&lt;/code&gt;</div>
