Cermant 10-Pack DC-DC Boost Converter Module, Mini 5V Step-Up Voltage Regulator Board (0.9-5V Input) for Electronics DIY Projects

["This ultra-compact (11x10.5x7.5mm) step-up converter board features a 2.54mm pin pitch. It is a passive electronic component that requires an external power source to function, converting lower DC input to stable 5V output.","Effortlessly boosts low voltage (0.9-5V DC) to a stable 5V DC output. With a 150KHz switching frequency and up to 480mA output, it efficiently powers your low-current devices.","Perfectly converts power from single-cell batteries (like 1.5V AA, 3V CR2032, or 3.7V Li-ion) to usable 5V for Arduino, sensors, LEDs, and other microcontroller projects.","An essential tool for makers, hobbyists, and engineers. Use it in wearable tech, portable chargers, IoT devices, or any project requiring stable 5V from lower voltage sources.","Each order includes 10 pieces of the boost converter board, perfect for multiple experiments, prototypes, or batch builds."]
