Board overview

PiJuice is a fully uninterruptable / uninterupted power supply that will always keep your Raspberry Pi

powered! It has a real time clock (RTC) for time tracking and scheduled tasks when the Pi is offline (as

well as remote on/off of your Pi). It also has an integrated microcontroller (MCU) chip which will

manage soft shut down functionality, a true low power deep sleep state and intelligent start up.

The tri-coloured RGB LEDs will allow you to keep track of the battery charge levels and other info (they

are programmable). There are also three programmable buttons which will allow you to trigger events

or customisable scripts aside from their predefined functions. PiJuice only uses five of the Pi's GPIO

pins (just power and I2C), the rest are free and made available via the stacking header which allows for

other boards to be used along side PiJuice. The board can be powered directly from the grid with the

standard Raspberry Pi PSU, via an on board battery, via external batteries, solar panels, wind turbines

and other renewable sources.

The board has a Raspberry Pi HAT compatible layout, with onboard EEPROM (you can disable the

EEPROM if you want also). It has been designed for the Raspberry Pi A+, B+, 2B and 3B but it is also

electrically compatible with the Raspberry Pi Zero v1.3 and Zero W v1.1 or any other Pi.

PiJuice is a fullyCE and FCC testeddesign andbattery safety testshave also been carried out for peace

of mind when using in educational or industrial settings.

Installing the software

PiJuice will actually work straight out of the box, with no software, to power the Pi and for some other

basic functionality. However to get the most out of PiJuice you really need to install the software

packages. For PiJuice we have created a Raspbian / Debian Package to make it extra simple to obtain

and install the necessary software. At the command line simply type:

sudo apt-get install pijuice-gui

After a restart a new icon "PiJuice Settings" will appear under Menu>Preferences.

If you wish to install just the light version of PiJuice with no GUI:

sudo apt-get install pijuice-base

PiJuice is compatible with any single cell LiPo or LiIon battery so bigger (or even smaller) batteries can be chosen especially depending on CPU load and connected hardware which may cause significant variations to the overall maximum up time of the Raspberry Pi.

2/12/2018 GitHub - PiSupply/PiJuice: Resources for PiJuice HAT for Raspberry Pi - use your Pi Anywhere Input voltage range - 4.2V – 10V Output voltage - 3.3V and 5V Output amperage - maximum current at 5V gpio is 2.5A and at VSYS output 2.1A, but also this depends heavily on battery capacity. For BP7X have measured around 1.1A at 5V GPIO and around 1.6A at VSYS output. Obviously this also depends heavily on the current draw demanded by the Raspberry Pi / device itself. To achieve maximum of 2.
