The Mini 360 DC-DC Step Down Buck Converter Module is a compact and efficient voltage regulator designed to step down higher DC voltages to lower, stable output levels. Based on the MP2307 IC, this tiny module can deliver up to 1.8A output current (with proper cooling) while maintaining high efficiency.
Despite its ultra-small size, the Mini 360 is widely used in DIY electronics, Arduino, ESP32/ESP8266, robotics, IoT devices, battery-powered projects, and portable gadgets where space is limited but stable voltage regulation is required. The output voltage is adjustable from 1V to 17V, making it versatile for powering microcontrollers, sensors, LEDs, and communication modules.
