Hiwonder Brick-Compatible Servo for micro:bit Projects This product combines two visually distinct, brick-compatible servos for creative micro:bit builds. Select the gray 270° variant when the project needs a commanded position, such as a small arm, gate, or pointer. Select the orange 360° variant when the project needs continuous drive with PWM-controlled direction and speed, such as a wheel or rotating mechanism. Important: these variants do not operate the same way. Color identifies the motion mode. Choose the Right Variant Variant Gray 270° Orange 360° Motion type Positional servo Continuous-rotation servo What the signal controls Target angle from 0–270° Direction and speed Can it hold a commanded angle? Yes, within its 270° range No Continuous rotation No Yes Color Gray Orange Key Features Two distinct motion modes: choose precise 0–270° positioning or continuous 360° rotation according to the mechanism. micro:bit project support: the manufacturer describes micro:bit program control when used in a compatible controller-and-building-block setup. Brick-compatible form factor: housing studs, holes, and a cross-shaped output shaft support compatible building-block mechanisms. Three-stage gear set: the manufacturer describes tooth-skipping protection intended to reduce damage from excessive torque or forced twisting. POM housing: the enclosure is specified as environmentally friendly POM material. Technical Specifications Specification Gray 270° Variant Orange 360° Variant SKU Hiwoner-21100014 Hiwoner-21100013 Servo size 40 × 16 mm 40 × 16 mm Weight 12 g 12 g Working voltage 6V 6V Rotation range 0–270° positional control 360° continuous rotation Current 200 mA rated; 700 mA locked Not specified by the manufacturer Torque 500 g (manufacturer-listed value) 1 N·m (manufacturer-listed value) Orange 360° PWM Control Reference The continuous-rotation variant does not use PWM as a position command. The manufacturer’s reference maps pulse width to motion as follows: Pulse width Orange 360° response 500 µs 100% positive rotation 1000 µs 50% positive rotation 1500 µs Stop 2000 µs 50% reverse rotation 2500 µs 100% reverse rotation Frequently Asked Questions Which variant should I choose for a robotic arm or a moving pointer? Choose the gray 270° variant. It is the positional version and accepts a commanded angle within its 0–270° range. Can the orange 360° variant move to and hold 90° or 180°? No. The orange variant is a continuous-rotation servo. Its control signal sets direction and speed, not an absolute output angle. A 1500 µs pulse is the listed stop point. Can I power either servo directly from a micro:bit? No. Both variants are specified for 6V operation. Use an appropriate compatible controller and 6V power path for a micro:bit build rather than the micro:bit's logic-power output. Are micro:bit, controller, and building blocks included? The product is sold as servo variants. The manufacturer describes micro:bit control in a compatible build, but this listing’s variants do not state that a micro:bit, controller, or building blocks are included. Are these compatible with LEGO bricks? The manufacturer states compatibility with LEGO-style brick studs, holes, and standard cross-hole interfaces. Confirm fit before using components from other building-block systems.
