Buck-Boost Converter Board SparkFun

Adjustable Buck-Boost DC-DC Converter For Stable Power Management In Embedded And IoT Projects
The SparkFun Buck-Boost Converter is a versatile DC-DC power module designed to deliver stable and efficient voltage regulation for embedded systems, IoT devices, and portable electronics. It supports both step-up and step-down functionality, making it well-suited for applications where input voltage varies.
With an input range of 3 to 16V, the SparkFun Buck-Boost Converter can regulate output voltage between 2.5 to 9V. It includes selectable preset outputs of 3.3V and 5V, along with a custom-output option using an external resistor for flexible voltage configuration.
This switching-based buck-boost converter offers high efficiency up to 95%, reducing heat generation compared to linear regulators. Built-in over-temperature protection and support for an optional heatsink ensure reliable performance in demanding environments.
GPIO pins are broken out for added control, making the SparkFun Buck-Boost Converter suitable for advanced power-management applications in development boards and custom hardware designs.
