Unlock Stable Power for Your DIY Projects

The S09 DC-DC Automatic Buck-Boost Power Module is an essential component for compact electronics. Whether your input voltage is higher, lower, or equal to the output, this intelligent board automatically steps up or steps down the voltage to maintain a stable output. It is perfect for battery-powered applications (like Lithium-ion) where voltage drops as the battery drains.

Key Features:

• Automatic Regulation: Seamlessly switches between Buck (step-down) and Boost (step-up) modes.
• Wide Input Range: Supports DC 3V to 15V input, making it compatible with various battery configurations.
• Selectable Output: Available in fixed 3.3V or 5V output configurations.
• Compact Design: Ultra-small form factor (19mm x 14mm) fits into the tightest enclosures.
• High Efficiency: Ideal for extending battery life in portable devices.
