What ALISHA MKE-J Does
ALISHA MKE-J is an ESP32-C3 control board with a JQ6500 MP3 module built directly onto the board ? pre-loaded with sound effects from the factory. One board handles:
- Up to 3 MG90S servo motors ? faceplate open/close
- 2 PWM LED eye outputs ? brightness control built in
- 2 NeoPixel outputs ? pixel 1 pre-programmed for an 8×8 (64-pixel) NeoPixel panel arc reactor effect (panel not included)
- JQ6500 ? plays pre-loaded Iron Man sound effects through a connected speaker; no SD card required
All controlled by a single button with three gesture modes.
One Button. Three Gesture Modes.
| Gesture | Action |
|---|
| Tap | Opens / closes the faceplate |
| Double-tap | Toggles LED eyes on / off |
| Press & Hold | Adjusts LED eye brightness |
MKE-J vs. MKE-D ? Which Should I Get?
| MKE-J (this listing) | MKE-D |
|---|
| Sound module | JQ6500 | DFRobot DFPlayer |
| Sound files | Pre-loaded ? works immediately, no SD card needed | Load your own MP3s onto a microSD card (not included) |
| Customization | More technical ? requires special software to change sounds | Easy ? swap MP3 files on the SD card |
| Best for | Builders who want sound working out of the box | Builders who want to choose their own Iron Man audio |
Choose MKE-J if you want everything working immediately ? sounds are pre-loaded and the board is ready to go.
Choose MKE-D if you want to load your own Iron Man sound effects ? just drop MP3 files onto a microSD card.
