Description
Product Description: This compact DC-DC step-up converter module is designed to boost input voltages as low as 0.9V up to a stable 5V output via USB. Using Pulse Frequency Modulation (PFM) technology, it is highly efficient at low input voltages, making it ideal for portable and battery-powered projects. With its USB-A output port, it can power small 5V devices like microcontrollers, sensors, and low-power USB gadgets from single-cell batteries or other low-voltage sources. Great for prototyping, DIY electronics, and power supply applications where space is limited. Key Features: Boosts input voltage (0.9V–5V) to a regulated 5V output USB-A output for direct connection to USB-powered devices High efficiency with low input voltage (starts from a single AA battery) Compact, lightweight design suitable for small enclosures or breadboards Built-in protection features for safe
