Compact 5V USB humidifier driver board and atomization plate designed for easy integration into DIY humidifier projects. Stable, lowpower operation and durable atomizing disc deliver reliable mist in travel and smallspace applications. Key benefits Easy integration: Compact driver board fits small DIY enclosures and projects for fast prototyping and retrofit. Low power, reliable mist: 5V USB operation with 300mA current and 2W power consumption provides consistent atomization without heavy power draw. Efficient atomization: Stable 110KHz driving frequency and optimized waveform deliver energytomist conversion for consistent fog output and reduced waste. Durable atomizing disc: Round ring plate with centerspray layout, 740 ultradense spray holes and 5μm apertures, silvercoated oxidationresistant surface to resist corrosion from continuous moisture. Travelready and compatible: Works with any standard 5V USB power source for immediate atomization startup in portable or smallspace environments. Technical highlights Power: 5V USB input, 300mA current, 2W power consumption Drive frequency: 110KHz for efficient operation of the atomizing disc Size: 46*20*17mm/.81*0.79*0.67' Atomization disc: Round ring plate, center spray layout, 740 ultradense spray holes, 5μm apertures Surface treatment: Oxidationresistant silvercoated surface on the atomizing disc Performance: Optimized waveform output and electronic design for energytomist conversion and longterm reliable use Why this product solves common problems Avoids bulky power requirements: USB 5V operation removes need for specialized power supplies. Consistent startup and output: frequency drive and optimized waveform ensure immediate and stable atomization. Lasting performance in humid environments: Silvercoated disc and durable board design reduce erosion and performance drop over time. Small footprint for compact designs: Tiny dimensions make it easy to fit into portable humidifiers, desktop units, or enclosed DIY builds. Typical applications Travel humidifiers and portable mist makers powered from power banks or USB chargers. Desktop or bedside humidifiers for small rooms, offices, or workstations. DIY terrarium, plant humidification, or hobby projects that require compact, lowpower atomization. What's included (as described) 5V USB powered mist maker driver board Atomization plate with the specified hole density and surface coating Compatible with any standard 5V USB power source. Designed for straightforward integration and dependable, lowpower mist generation in a variety of smallscale humidification projects.
