The Zero2Go Omini is a multi-channel power supply board that sits on top of any Raspberry Pi with a 2×20 header. It accepts up to three separate power inputs and automatically selects the one with the highest voltage, making it perfect for projects that need backup power or flexible power source options.
The on-board buck-boost converter accepts 3.5–28V DC on any input and regulates it to a clean 5V output at up to 2A — enough for larger Pi models with displays, radios, or sensors attached. An indicator LED shows blue for step-up/pass-through mode or green for step-down mode.

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.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
- USB Type-C
- A reversible USB connector used for power and data on many modern devices. On this kit it indicates an alternate 5V power input, which may be useful for setup or charging without the solar panel.
