Description:
The MT3608 DC-DC step-up booster power module is a compact and efficient voltage boost converter designed to increase low DC input voltages to higher adjustable output voltages. Powered by the reliable MT3608 chipset, this module can convert input voltages ranging from 2V to 24V into adjustable output voltages up to 28V, making it ideal for Arduino, ESP32, Raspberry Pi, battery-powered devices, IoT systems, robotics, and DIY electronics projects.
With a maximum output current of 2A, high conversion efficiency of up to 93%, and a small form factor, the MT3608 boost converter is perfect for portable and embedded applications where stable power delivery is essential. The onboard precision potentiometer allows easy output voltage adjustment, enabling users to power sensors, displays, wireless modules, motors, and other electronic components with ease.
Whether you're boosting a single lithium battery to 5V USB power or creating a custom power supply for your electronics project, the MT3608 module offers a reliable, cost-effective, and energy-efficient solution.
IMPORTANT NOTE:
- Output voltage must be adjusted using the onboard potentiometer before connecting sensitive devices.
- The output voltage must always be higher than the input voltage.
- For high-current applications, additional cooling may be required.
