Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> The Waveshare Rotation Sensor is an incremental rotary encoder that converts rotation into digital pulse trains. It operates at 3.0–5.3 V, provides 20 pulses per revolution, and measures 32.0 × 15.0 mm.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/9533 9533 – Rotation Sensor]<br /> * [https://shop.jw-tech.eu/p/WSAL9533 WSAL9533 – Rotation Sensor]<br /> <br /> == Technical overview ==<br /> * Operating voltage: 3.0 V to 5.3 V.<br /> * Pulses per revolution: 20.<br /> * Dimensions: 32.0 mm × 15.0 mm; mounting hole diameter 2.0 mm.<br /> * Principle: Incremental encoder counts pulses for both clockwise and counterclockwise rotation; unlike a potentiometer, the number of rotations is unlimited.<br /> * Pinout for MCU use: VCC ↔ 3.0–5.3 V, GND ↔ power ground, SW ↔ MCU IO (button state), SIB ↔ MCU IO (output state), SIA ↔ MCU IO (output state).<br /> * Waveform verification: Connect SIA, SIB, and SW to CH5, CH6, and CH7 on a logic analyzer to inspect clockwise, counterclockwise, and button-press signals.<br /> <br /> == Notes and version constraints ==<br /> * The source lists general Pico, STM32, and Arduino setup sections but no concrete code examples or exact commands; verify before use.<br /> * Flashing Pico2 firmware from MicroPython may cause the device to become unrecognized; the source recommends using the provided firmware library instead.<br /> * CMake files must not contain Chinese characters (including comments), otherwise project import may fail.<br /> * The referenced Arduino-Pico core URL points to release 4.0.2; updates require manual verification.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/Rotation_Sensor Rotation Sensor - Waveshare Wiki]<br /> * Source revision: 69231<br /> * Captured: 2026-08-29T09:44:53+00:00<br /> * SHA-256: &lt;code&gt;d25e7cc8452f2eff6cedf51a4a79ce211f16aaaf0396c911aad8d451d213c6f4&lt;/code&gt;</div>
