Effortlessly Power Your Projects with a Mini 1-5V to 5V Boost Module This compact DC-DC step-up converter is the perfect solution for powering 5V devices from low-voltage sources like batteries. Whether you're working on a DIY electronics project, a portable charger, or an Arduino circuit, this module provides a stable 5V output. Its ultra-small size makes it easy to integrate into any design. Key Features: Input Voltage: 0.9V to 5V (from single AA, AAA, or lithium batteries) Output Voltage: 5V Max Output Current: Up to 480mA High Efficiency: Typical conversion efficiency of 85% Operating Frequency: 150KHz Dimensions: 11mm x 10.5mm x 7.5mm (ultra-compact) Important Usage Notes : Please Note: For optimal performance and to prevent module burnout, ensure: The input voltage is not greater than 5V. The input power is always greater than the output power. The output load current does not exceed the nominal 480mA.
