MT3608 DC-DC Step-Up Boost Converter

Micro USB Input · 2A · 2–24V to 5–28V Adjustable

Overview

A compact, high-efficiency step-up (boost) converter module based on the MT3608 IC, with a Micro USB input connector for powering directly from the abundance of Micro USB cables and chargers most workshops already have to hand. The output is fully adjustable via the onboard multi-turn trimmer potentiometer, giving you anywhere from 5V up to 28V from input voltages as low as 2V. Ideal for Arduino, Raspberry Pi, LED drivers, battery-powered projects and small DIY power supplies.

Key Features

  • Micro USB input – use any standard Micro USB cable or phone charger
  • Wide input range – works from 2V right up to 24V
  • Adjustable output – 5V to 28V via the onboard trimmer
  • Up to 2A output current (max load depends on input/output ratio)
  • Up to 93% efficiency at typical loads
  • Compact PCB – fits neatly into project enclosures and breadboards
  • Solder pads also provided for direct wired input if preferred

Typical Applications

  • Powering Arduino, ESP32, Raspberry Pi and other microcontroller projects
  • Boosting battery voltage (Li-ion, Li-Po, AA packs) to 9V, 12V or higher
  • Driving LED strips and small motors that need a higher rail
  • Portable battery-powered tools, lamps and gadgets
  • Hobbyist DIY bench supplies and breadboard rails

Important Notes

Set the output before connecting your load. Apply input power, measure the OUT pins with a multimeter, and turn the trimmer screw until you reach the voltage you need. The output must always be higher than the input — this is a boost converter only, it cannot step voltage down.

Maximum 2A output is achieved at lower step-up ratios. Drawing the full 2A at the highest output voltages will exceed the IC's thermal rating; size your project accordingly.
