New tutorial in the Adafruit Learning System: Battery Powered Raspberry Pi Displays w/RaspiRobot Shield
Power a Raspberry Pi and LED matrix display using a RasPiRobot Board
Although the RasPiRobot Board is primarily intended as a motor controller, it also includes a high current switch mode voltage regulator that allows you to power a Raspberry Pi from a wide range of battery types.
In this tutorial you will learn how to use the RasPiRobot Shield and an AA battery pack to make a portable Raspberry Pi powered display.
The display will show the current time as scrolling text, but the project can easily be modified to display other scrolling text messages.
