This tiny little servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds you're used to but smaller. You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. Of course, it's not nearly as strong as a standard servo. Works great with the Motor Shield for Arduino, or by just wiring up with the Servo library. Comes with a few horns and hardware.
This servo is just like our classic Micro Servo but has a 3 pin JST PH cable at the end! This makes it perfect for plug-and-play support with any of our boards that have 3-pin STEMMA connectors, like the PyPortal, HalloWing, PyGamer/PyBadge, etc! So you can just plug right into the connector and get twistin'
To control with an Arduino, we suggest using the Servo library included with the Arduino IDE (see here for an example sketch). Position "0" (1.5ms pulse) is middle, "90" (~2ms pulse) is all the way to the right, "-90" (~1ms pulse) is all the way to the left. For CircuitPython, check out this guide. MakeCode also has Servo support.
The 19cm-long JST cable is color-coded:
- Black for GND
- Red for 5V
- White for Data
Note that the default servo pulse widths (usually 1ms to 2ms) may not give you a full 180 degrees of motion. In that case, check if you can set your servo controller to custom pulse lengths and try 0.75ms to 2.25ms. You can try shorter/longer pulses, but be aware that if you go too far you could break your servo!
Jargon buster
Plain-language definitions for the technical terms used above.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- JST PH
- A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
