Features: 1. The product is made of high-quality materials, with stable spray performance and guaranteed quality 2. This is an upgraded version of the atomization driver module. After the upgrade, the Type-c USB interface is more convenient to use, and it can also be connected to an external 2PIN cable. At the same time, it is also suitable for makers to use a microcontroller to directly input power for power supply 3. Power on the power input spray, which is suitable for the work of the atomizing equipment when it is powered on 5. It has the characteristics of large fog volume, fine fog particles, high fog spraying, and fine and silent moist fog   Parameter: Product name: Atomization drive circuit board Model: QDB-1 USB interface: Type-c Rated voltage: DC5V Rated current: 300mA Power: 1.5-2W Resonant frequency: 108-110KHz Material: 1.2mm FR-4 PCB size: 29.5 × eighteen point six × 7mm Precautions: 1. Do not turn on the atomizer without connecting it 2. It is not allowed to modify the circuit board without permission 3. Do not overload the input power supply 4. The circuit board should not be exposed to water or moisture 5. Must be used together with the same frequency fog film Package include: Module X1 Atomiser X1 Cotton core X1 Shell Accessories X2
