The SparkFun Buck-Boost Converter is a handy power accessory board that allows you to fine tune the amount of power your project receives. This converter can take an input voltage of anywhere from 3-16V which can then be regulated to an output voltage between 2.5-9V. With the switch on the bottom of the board, you can set the common output voltages of 3.3V and 5V, but we've also added a custom setting that allows you to solder a resistor based on your custom voltage needs. The GPIO pins have also been broken out along the top of the board for even more control!
In addition to the voltage control, the SparkFun Buck-Boost Converter uses a switching DC/DC converter, which is more efficient than a linear regulator. More efficiency means less energy is wasted in the form of heat. With built-in overtemperature protection and an optional heatsink, you can achieve up to 95% efficiency rating.
Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a power circuit that raises a lower input voltage to a higher output voltage. It matters here because the board can power a sensor that needs a higher supply voltage while still using a single connector for power and data.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
