ServoTalk · Three servo outputs
Give your character a voice—and expression.
Make a mouth follow your audio while the eyes and head move with adjustable random animation. ServoTalk combines three RC servo outputs with RGB NeoPixel eye control in one compact character controller.
What’s includedCompare controllersWatch setup videosThree outputs. One expressive character.
1 · Mouth
The mouth servo responds to your audio in real time. Adjust the open and closed positions, speed, and audio sensitivity to suit your mechanism.
2 · Eyes
Animate the eyes with adjustable random movement. Activity increases while your character is talking.
3 · Head turn
Add side-to-side head movement with adjustable travel limits and speed. The character’s mechanics and servos determine the movement available.
At a glance.
| Servo outputs | 3 RC servo outputs: mouth, eyes, and head turn |
| Eye lighting | RGB NeoPixel control with adjustable color, brightness, and behavior |
| Audio connection | 3.5 mm stereo audio input from your own source |
| Audio playback / amplifier | External audio source and powered speakers or amplifier required; no built-in audio storage or amplifier |
| DMX | No — choose ServoDMX for a DMX-controlled servo setup |
| Supplied power | 5 VDC power supply included |
| Setup | Calibrate servo travel limits for your own mechanism before use |
Eye lighting and motion you can tune.
RGB NeoPixel eyes
Choose eye color and brightness, then select steady illumination, audio-responsive throbbing, or fade behavior. Use compatible NeoPixel eyes and follow the manual’s wiring and power limits.
Random animation and servo sleep
Adjust idle eye and head movement to suit your character. Configurable servo sleep allows servos to relax during inactivity when your mechanism does not need them to hold position.
What’s included—and what you supply.

- 5 VDC power supply
Build your setup
- Compatible RC servos and character mechanics
- Your audio playback source and prepared audio

Check cable requirements for your source before ordering.
Get the best result from your audio.
For one character, put the voice in the left channel and music or sound effects in the right. The mouth follows the left audio channel. Keeping other sounds separate prevents them from driving unwanted jaw movement.
No specially encoded track or computer programming is needed for the built-in audio and random-movement operation. A new installation still needs its servo travel limits calibrated to the character.
From controller to character.
- Install and calibrate the servos. Follow the operating manual to center the servos and set travel limits within your mechanism’s range.
- Connect the audio and lighting. Use your prepared stereo track and compatible NeoPixel eyes.
- Connect the supplied power and tune the performance. Adjust audio sensitivity, movement, and eye settings for your character.
ServoTalk or ServoDMX?
| ServoTalk | Three servo outputs for an audio-responsive mouth, eye movement, and head turn. A straightforward choice for a talking character without DMX. |
| ServoDMX | Eight enabled servo outputs in the base configuration with optional expansion, configurable motion limits, and DMX integration for more complex characters. |
Questions before you order.
Does this include a skull or servos?
This listing is for the controller and supplied power supply. For an assembled character with its controller installed and calibrated, explore our Standard Talking Skull or Head Turn skull.
Can it store or play my audio?
Use a separate audio playback source. ServoTalk responds to incoming audio; it does not replace an audio player or speaker amplifier.
Can two characters have a conversation?
A two-character setup can use separate voices in the left and right channels. Each character needs its own control and suitable audio routing. Ask us about your two-character setup.
