The Ultrasonic Mist Maker Driver Board Module is a compact, ready-to-use atomizer kit designed for DIY humidifiers, mist makers, and air quality projects. It combines a high-frequency driver circuit board with a 20mm atomization diaphragm (ceramic ultrasonic disc), powered by a standard 5V USB supply. This makes it an ideal solution for custom humidifiers, desktop misters, aromatherapy diffusers, and DIY electronics projects requiring reliable ultrasonic atomization.
At the heart of the kit is the atomization diaphragm — a 20mm ceramic ultrasonic disc that vibrates at high frequency (typically 108kHz–115kHz, depending on the specific variant) to break water into fine mist particles. The driver board generates the high-frequency oscillation signal required to drive the diaphragm, eliminating the need for separate modules and complex wiring. The kit is ready-to-use: simply connect the diaphragm to the driver board, immerse it in water, and apply 5V USB power to begin misting.
The 5V USB power input makes the kit extremely convenient to use — it can be powered from any USB port, power bank, phone charger, or computer. The low power consumption (typically 2W–2.5W) is suitable for portable and battery-powered applications, while still producing a visible, consistent mist output suitable for small spaces.
The kit includes the atomization diaphragm and the driver board, with pre-attached wiring for easy connection. The compact PCB design allows integration into small enclosures, bottles, and custom housings. The atomization diaphragm is designed for continuous operation when properly immersed in water, with a typical lifespan of 3000–5000 hours.
The kit is widely used in DIY humidifiers, aromatherapy diffusers, desktop misters, miniature fog machines, model-making effects, air quality projects, and educational science projects. It is also popular in commercial product development for small appliances and personal care devices.
Important Note: The atomization diaphragm must be fully immersed in water during operation. Do not operate the atomizer dry, as this will cause overheating and permanent damage. Use clean water (preferably distilled) to prevent mineral buildup on the diaphragm. The driver board should be kept dry and away from water.
Whether you are building a custom humidifier, designing an aromatherapy diffuser, or adding misting effects to a project, the Ultrasonic Mist Maker Driver Board Module provides a reliable, integrated solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
