Product Description

Zero2Go is a Raspberry Pi Zero sized (or pHAT shape) extension board that can work as wide input range power supply for Raspberry Pi. Zero2Go Omini is the second member in the Zero2Go family.

Zero2Go Omini supports all Raspberry Pi models that has the 40-pin GPIO header, including A+, B+, 2B, 3B, 3B+, Zero and Zero W.

The main features of Zero2Go Omini include:

  • Three separated input channels (each accepts 3.5~28V DC).
  • Auto step-up or step-down to output 5V for powering Raspberry Pi.
  • Auto switch input channel (one with highest voltage takes the priority).
  • Gracefully turn on/off Raspberry Pi with single tap on the button.
  • Fully cuts power for Raspberry Pi and all its USB peripherals after shutdown.
  • Long hold the button to force power cut, when OS loses response.
  • Monitor the input voltage on each channel (via software).
  • Shutdown Raspberry Pi when input voltage below preset threshold.
  • Recover Raspberry Pi when input voltage exceed preset threshold.

Zero2Go has quite wide input range (3.5V~28V), so it is convenient to power your Raspberry Pi with power bank, Li-Po battery pack, solar panel, car battery or different kinds of power adapters etc. You can also configure it as a UPS (please read user manual for more details).

How does it work? Please see below the simplified diagram. It demonstrates the main functionalities of Zero2Go Omini and can help you to understand how it works. When Vin is lower than 5.5V, the step-up engine will be used; When Vin is 5.5V or higher, the step-down engine will be used instead.. Zero2Go can switch between step-up and step-down modes automatically.

Software Installation

To install Zero2Go’s software, please run this command in your home directory:

pi@raspberrypi ~ $ wget http://www.uugear.com/repo/Zero2GoOmini/installZero2Go.sh

If your Raspberry Pi has internet connection, it will immediately download the script from our website, and you will then see the “installZero2Go.sh” script in your home directory. Then you just need to this script with with sudo:

pi@raspberrypi ~ $ sudo sh installZero2Go.sh

You will need to use sudo to run this script. This script will copy a file to “/etc/init.d/zero2go_daemon”, and register it to run after the boot.
