Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> The ST3020 is a dual-axis serial bus servo delivering up to 25 kg·cm of torque at 12 V and featuring a programmable 360° magnetic encoder. It accepts 6–14 V DC input, supports daisy-chaining up to 253 servos over the bus, and provides feedback on position, load, voltage, current, and temperature.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL24703 WSAL24703 – 25kg.cm Wide Range Voltage Serial Bus Servo, High Precision And Large Torque, With Programmable 360 Degrees Magnetic Encoder]<br /> <br /> == Technical overview ==<br /> * Input voltage: 6–14 V DC; can be powered directly from 2S or 3S lithium batteries.<br /> * Rotation angle: 360° in servo mode; continuous rotation available in motor mode.<br /> * Position sensor resolution: 0.088° (360°/4096).<br /> * Locked-rotor torque: 25 kg·cm (≈347.79 oz·in) at 12 V.<br /> * Idle speed: 60 RPM (0.167 s per 60°) at 12 V.<br /> * Bus ID range: 0–253; factory default ID is 1.<br /> * Feedback parameters: position, load, speed, input voltage, current, temperature.<br /> * Dimensions: 40.2 mm × 20.2 mm × 40 mm.<br /> * Each servo has two interfaces enabling daisy-chain connection of multiple units.<br /> * Controlled via an ESP32-based driver board using an Arduino demo; alternatively, an ESP32 flash download tool is provided for the driver board.<br /> <br /> == Notes and version constraints ==<br /> * The source contains no explicit command lines or API calls; therefore no commands are listed.<br /> * When assigning IDs, only one servo should be connected to avoid ID conflicts on the same bus.<br /> * Parameter changes require unlocking the EPROM area first; otherwise changes are lost after power loss.<br /> * Oversized mounting screws may contact the servo body, causing a sharp current increase that can burn out the servo.<br /> * The exact version of the Arduino IDE package (e.g., 2.1.0) and the precise dependency libraries should be verified before compiling.<br /> * For custom projects, the source refers to the serial bus servo driver schematic; full circuit details are not reproduced in the source.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/ST3020_Servo ST3020 Servo - Waveshare Wiki]<br /> * Source revision: 111163<br /> * Captured: 2026-09-05T02:45:14+00:00<br /> * SHA-256: &lt;code&gt;5eb22b9a96ba3a8b687ce34d31522743c4dd87bbd49eb4bf7dca2bc8519c6ded&lt;/code&gt;</div>
