Product Overview
2/12/2018 GitHub - PiSupply/PiJuice: Resources for PiJuice HAT for Raspberry Pi - use your Pi Anywhere
https://github.com/PiSupply/PiJuice 4/5
The board comes with an onboard 1820 mAh "off the shelf" Lipo / LiIon battery which guarantees
~4/6 hours of up time. 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. That's why
we have provided means to support bigger battery sizes like 5000 or 10,000 mAH+ to help your
PiJuice last up to 24 hrs +.
The batteries can be replaced without downtime as long as an alternative power source is provided in
the meantime. You could for example even use a battery bank whilst replacing either the onboard
battery or one connected to the screw terminal (you shouldn't connect a battery on board and to
screw terminal at same time though or you will fry your PiJuice). Using a standard PSU will of course
work too and that configuration is in fact ideal for a UPS setup.
GUI interface
An enhanced graphical user interface (GUI) is available via APT and provides a full power management
API for Raspbian that allows auto shutdown capability when running low on batteries.
It also provides a means to attach customisable scripts to power events and reporting of the battery
status. You can find out more in thesoftware section.
Technical specs summary
The EEPROM can be disabled and its I2C address changed for increased compatibility with other
boards

Optional spring pin - Mil-Max 0929-7-15-20-77-14-11-0 or 0929-7-15-20-75-14-11-0
Compatible with any 4 pin battery on board that can be used with 00-9155-004-742-006 battery
contacts from AVX including the BP7X, BP6X, and any compatible batteries including the
1600mAh and 2300mAh ones from CameronSino (CS-MOA853SL and CS-MOA855XL)
There is an on board 4 pin screw terminal block for larger off board batteries. Any single cell LiPo
/ LiIon is compatible. However, you use your own sourced battery at your own risk. We HIGHLY
RECOMMEND using a battery with an internal protection circuit and a NTC (temp sensor)
Optional header for offboard button - connected to same output as SW1
6 pin breakout header - with two GPIO from the ARM Cortex-M0, Vsys, 5v0, 3v3, GND
connections
Header for optional off board solar panel / wind turbine etc.
Optional RF Shield attachment - Harwin S02-20150300 (can also double as an inexpensive
heatsink)
