What it is
The ShillehTek MT3608 DC-DC Step Up Boost Converter 2A Adjustable Power Module is a compact switch-mode regulator that boosts low-voltage sources (for example a 3.7V Li-ion cell) up to common project rails such as 5V, 9V, or 12V for Arduino boards, Raspberry Pi accessories, sensors, and small motors.
Pins
Refer to the silkscreen labels on the module and the listing photos for exact pin names and polarity. Most MT3608 boost modules expose input power pads and output power pads—double-check labels before wiring to a battery, Arduino, or sensor rail.

Frequently Asked Questions
How do I set the output voltage on the MT3608 boost converter?
Power the module from your input source, then measure the output with a multimeter while turning the multi-turn trimpot slowly to fine-tune the voltage. Make small adjustments and re-check before connecting your Arduino, sensor, or motor load.
Why is the MT3608 potentiometer not changing the voltage?
This module uses a precision multi-turn trimmer, and it may require roughly 15–20 counter-clockwise turns before the output voltage begins to change. Keep a meter on the output while adjusting.
Can I boost a single 3.7V Li-ion battery to 5V for Arduino projects?
Yes—this MT3608 DC-DC step-up module is commonly used to raise a single-cell Li-ion (around 3.7V nominal) to a 5V rail. Verify the output voltage under load with a multimeter before connecting sensitive boards.
What input and output voltage range should I expect from this MT3608 module?
It’s intended for low-voltage inputs (around 2V and up) and provides an adjustable boosted output commonly used up to about 28V. Exact usable range depends on your load and input source.
Is this boost converter suitable for motors and sensors?
It can be used for motors and sensors in portable builds, but current draw varies widely. Start by testing your load, watch for voltage drop, and keep wiring short to reduce losses.
