NEW PRODUCT – Micro Servo with 3-pin JST Cable – STEMMA Connector Compatible

NEW PRODUCT – Micro Servo with 3-pin JST Cable – STEMMA Connector Compatible


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 & gearbox, 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 in to 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!

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
