‘Pi Power’ Handles Power Management & Control for Portable Pi Projects #piday #raspberrypi @Raspberry_Pi

here on GitHub detailing some effective power management solutions for portable Raspberry Pi projects, demonstrated using a Raspberry Pi Zero. Bullet points below sum up the incentives for integrating ‘Pi Power’ within your designs. (Thanks to Robert Jones for sending this in.)

The Raspberry Pi is a low cost, single board computer with reasonable performance and relatively low power consumption, typically a version of the Linux operating system, often Raspbian.

The Pi family of boards have turned out to be very useful machines for standalone and/or portable projects such as remote environment monitoring, cameras, etc.

But to be truly portable, a system needs to include a power source and a way to control that power – such as a rechargeable battery, a charger, an on/off switch and some way to monitor battery status.

What I want is something equivalent to the way my iPhone works

  • To power it up from a cold state, press a button for a few seconds
  • To power it off, press the same button for a few seconds
  • Indicate how much power remains in the battery
  • Provide an alert when that is running really low
  • Shut down safely without any data corruption if the battery does run out
  • To recharge the battery, just plug in a cable from a USB charger
  •  
    This project provides one approach to reaching this goal, building on the LiPoPi project from Daniel Bull.

    Pi Power has been tested successfully on these boards:

  • Raspberry Pi 2 Model B V1.1 (2014)
  • Raspberry Pi Zero v1.2 (2015)
  • Raspberry Pi 3 Model B V1.2 (2015) – using the Pi 3 modification shown above
  •  
    Please take a look at the Wiki for more background on battery charging, power usage by the Pi etc.
