3.7V to 5V 7V 9V Boost Board Fan Motor Speed Controller Board Type C Rechargeable Fan Circuit Board Governor Step Up Module

Product Features:1. Compact design: The control board adopts a miniaturized design, making it suitable for installation in devices with limited space.2. Boost conversion function: Built in boost circuit, can boost from lower battery voltage (such as 3.7V lithium battery) to meet the working requirements of fan motor3. Low standby current: In standby mode, the current consumption of the control board is extremely low (such as 10uA), which helps to extend the device's battery life.4. Multi voltage output support: This voltage boosting plate can boost the battery voltage to various output voltages such as 5V, 7V, 9V, 12V, etc.5. Wide range of use: This type of control board is widely used in small handheld fans powered by lithium batteries, suitable for the design requirements of portable devices.
