This is a compact ultrasonic mist maker module powered over USB Type-C at 5V. It drives four microporous atomizer discs at once and produces fine, cool mist for humidifiers, terrariums, plant misting, tabletop fountains and decorative fog effects. It is plug-and-play: connect the atomizers, add a water wick, plug in a 5V Type-C source and choose a spray mode with the onboard button.
Key Features
-
USB Type-C, 5V input. Runs from a phone charger, power bank or PC USB port.
-
4-channel output. Drives four atomizer discs at the same time for high mist volume.
-
Multiple spray modes. All-on, dynamic (alternating heads), single and multiple spray, selected with the onboard button.
-
Microporous atomizer plates. Ultra-fine mist that doesn’t wet the surface around it.
-
Auto shut-off timer. Stops continuous misting automatically to prevent dry running and save power.
-
2.0mm plug-in terminals. Atomizers connect without soldering.
-
Compact PCB (~50 × 25 mm). Easy to build into DIY enclosures.
