It supports Raspberry Pi Zero and other Raspberry Pi models who have 40-pin header.\u003c\/p\u003e\n\u003cp\u003eZero2Go 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 Rev2 is the third member in the Zero2Go family.\u003c\/p\u003e\n\u003cp\u003eZero2Go Omini supports all Raspberry Pi models that has the 40-pin GPIO header, including A+, B+, 2B, 3B, 3B+, 3A+, Zero, Zero W and 4B.\u003c\/p\u003e\n\u003cp\u003eThe main features of Zero2Go Omini include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThree separated input channels (each accepts 3.5~28V DC).\u003c\/li\u003e\n\u003cli\u003eAuto step-up or step-down to output 5V for powering Raspberry Pi.\u003c\/li\u003e\n\u003cli\u003eAuto switch input channel (one with highest voltage takes the priority).\u003c\/li\u003e\n\u003cli\u003eGracefully turn on\/off Raspberry Pi with single tap on the button.\u003c\/li\u003e\n\u003cli\u003eFully cuts power for Raspberry Pi and all its USB peripherals after shutdown.\u003c\/li\u003e\n\u003cli\u003eLong hold the button to force power cut, when OS loses response.\u003c\/li\u003e\n\u003cli\u003eMonitor the input voltage on each channel (via software).\u003c\/li\u003e\n\u003cli\u003eShutdown Raspberry Pi when input voltage below preset threshold.\u003c\/li\u003e\n\u003cli\u003eRecover Raspberry Pi when input voltage exceed preset threshold.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eZero2Go 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 \u003ca href=\"http:\/\/www.uugear.com\/doc\/Zero2Go_Omini_UserManual.pdf\" target=\"_blank\"\u003euser manual\u003c\/a\u003e for more details). \u003cstrong\u003eRemarks:\u003c\/strong\u003e Zero2Go Omini doesn’t charge the connected battery\u003c\/p\u003e\n\u003cp\u003eHow 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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/howitworks_480x480.png?v=1631020163\"\u003e\u003c\/p\u003e\n\u003ch2\u003eSOFTWARE INSTALLATION\u003c\/h2\u003e\n\u003cp\u003eTo install Zero2Go’s software, please run this command in your home directory:\u003c\/p\u003e\n\u003cp\u003e\u003ccode\u003epi@raspberrypi ~ $ wget http:\/\/www.uugear.com\/repo\/Zero2GoOmini\/installZero2Go.sh\u003c\/code\u003e\u003c\/p\u003e\n\u003cp\u003eIf your Raspberry Pi has internet connection, it will immediately download the script, and you will then see the “installZero2Go.sh” script in your home directory.

Zero2Go Omini uses GPIO-4 to receive shutdown command, if GPIO-4 is also assigned to 1-Wire, Zero2Go’s software will receive shutdown command unexpectedly. If your Raspberry Pi always automatically shutdown itself after installing Zero2Go’s software, that most probably due to the confliction with 1-Wire interface.\u003c\/p\u003e\n\u003cp\u003eWhen this happens, you most probably can not login your Raspberry Pi because it always shuts itself down before you get the chance to login. To solve this problem, you will need to take out the micro-SD card on your Raspberry Pi, and access its file system via a card reader. You need to edit the config.txt file in the “boot” volume to change the GPIO pin used by 1-Wire interface, or you can disable 1-Wire interface if you don’t need it for now. You need to find something like “dtoverlay=w1-gpio” in the file.\u003c\/p\u003e\n\u003cp\u003eIf you want 1-Wire to use GPIO-18, just change “dtoverlay=w1-gpio” to:\u003c\/p\u003e\n\u003cp\u003e\u003ccode\u003edtoverlay=w1-gpio,gpiopin=18\u003c\/code\u003e\u003c\/p\u003e\n\u003cp\u003eIf you want to disable 1-Wire interface, just comment it out:\u003c\/p\u003e\n\u003cp\u003e\u003ccode\u003e#dtoverlay=w1-gpio\u003c\/code\u003e\u003c\/p\u003e\n\u003cp\u003eSave the file and eject your micro SD card, and put it back to your Raspberry Pi.
