Bring your droid to life.
DroidFX turns an ESP32-S3 into the controller for your droid's lights, sounds and servo moves. Set everything up from a web page on your phone, then run the show from your transmitter.
Everything your droid does, in one place.
Lights, sound and motion, all controlled from your radio and set up in your browser.
45-button pad
Three pages of fifteen buttons, mirrored on your FrSky ETHOS radio's touch screen. Each one can toggle, hold, fire once or stop everything.
Button Pad guide →Timed sequences
Sound at 0 s, lights at 0.5 s, the dome turns at 1 s, all on one timeline, played by a single button press.
Sequences guide →Lights that know their shape
Strips, rings, jewels and panels. Fourteen effects follow your real layout, plus scrolling text in standard or Aurebesh.
LED guide →Sound, catalogued
Every track's name and length from one scan, your own labels, random or in-order playback, and a startup sound.
Sound guide →Servo moves
Find each servo's limits by moving it, then pose your droid on a timeline. Up to 16 servos.
Servos guide →● Display mode
next chatter 22 s
Idle & display mode
Left alone, your droid chatters and glows. On display with the transmitter off, the lights and sound keep going and the servos stay still.
Startup & idle guide →From parts to a performing droid in an afternoon.
No programming and no software to install. The board walks you through its own setup.
Wire it
An ESP32-S3 board, your receiver, and whatever your droid has: lights, a sound module, servos. Diagrams for each part.
What you need & wiring →Install
Plug the board into your computer and press Install in Chrome or Edge. The website installs DroidFX for you.
Install DroidFX →Set it up
Join the droid's WiFi on your phone. The setup wizard asks what you have, finds your radio switches as you flip them, and tests every light.
Getting started →One button. The whole performance.
- 1Servo lanesDrag keyframes to set where each servo is and when. It glides smoothly between them.
