Product Description (Detailed):

Unlock new possibilities for your electronic projects with the MT3608 2A Max DC-DC Boost Converter Module, an incredibly versatile and compact adjustable step-up power supply. This highly efficient module is an essential tool for anyone needing to convert a lower DC input voltage into a higher, stable DC output voltage, making it indispensable for a myriad of applications from powering microcontrollers with battery sources to creating custom power solutions for portable devices.

At its core, the MT3608 chip is a high-efficiency synchronous rectified step-up converter, designed to deliver impressive performance in a miniature footprint. Typically accepting an input voltage range from 2V to 24V DC, it can efficiently boost this to an adjustable output voltage ranging from 5V up to 28V DC, all while handling a maximum output current of 2 Amperes (with proper heat dissipation). This makes it ideal for stepping up 3.7V Li-ion battery voltage to 5V for Arduino or ESP32 boards, or boosting 12V to 24V for various sensors and motors. The module's high switching frequency (often around 1.2MHz) allows for the use of smaller inductors and capacitors, contributing to its compact size and higher efficiency, often exceeding 90%. Adjustment of the output voltage is straightforward, achieved via a multi-turn precision potentiometer (trimmer potentiometer) onboard, allowing for fine-tuning to your exact power requirements. With built-in features like soft-start, over-temperature protection, and current limit protection, the MT3608 module offers not only robust performance but also enhanced safety for your sensitive electronics. Whether you're building portable gadgets, developing IoT devices, or optimizing power consumption in your circuits, the MT3608 Boost Converter provides a reliable, efficient, and flexible power solution.

The MT3608 DC-DC Boost Converter Module is a compact, high-efficiency step-up power supply module designed to convert lower voltage DC sources (like 3.7V Li-ion batteries) into higher output voltages, up to 28V.

Powered by the MT3608 IC, this module can output up to 2A current, depending on input/output voltage difference and heat dissipation. The onboard potentiometer allows precise voltage tuning, making it suitable for charging circuits, Arduino projects, sensor arrays, and low-voltage power regulation.
