MT3608 DC-DC Boost Converter 2-24V to 5-28V 2A

The MT3608 is a high-efficiency, ultra-compact boost converter that steps up any input from 2 V to 24 V to a regulated output of 5 V to 28 V — at over 93% efficiency and up to 2 A. Small enough to fit on a fingertip but powerful enough to run from a single AA battery, it's the go-to module when you need more voltage in a tight space.

🔹 Key Applications

• Boosting single-cell LiPo (3.7 V) to 5 V for USB-powered devices
• Generating 12 V from a 5 V USB source for small relays and sensors
• Portable electronics projects powered by AA or AAA batteries
• IoT devices requiring higher voltage from low-voltage battery packs
• Wearable electronics with compact power requirements

🔹 Why Choose This Module?

• Over 93% efficiency — exceptional for such a compact module
• 2 V minimum input — works even with nearly depleted batteries
• Tiny footprint (37 × 17.3 mm) — fits in the most space-constrained designs
• Onboard potentiometer — simple screwdriver output voltage adjustment
• Stable output up to 28 V — headroom for a wide range of applications

🔹 What's Included

1 × MT3608 Boost Converter Module

🔹 Pro Tip

💡 Before testing, rotate the potentiometer fully counter-clockwise (15+ turns) to set the output to minimum before connecting your load — this prevents overvoltage damage. Ideal for boosting single-cell LiPo packs to 5 V for Arduino Nano or ESP8266 projects.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
