1. Introduction
BeagleBone Green (BBG) is based on the classical open-source hardware design of BeagleBone
Black (BBB) and added two Grove connectors.
It has removed the HDMI port on the BBB and also updated the 5V barrel to Micro USB host. It is
a low-cost, community-supported development platform for developers and hobbyists.
Boot Linux in under 10 seconds and get started on development in less than 5 minutes with just a
single USB cable.

3. Hardware Overview
Seeed.cc's BeagleBoneGreen page documents all of the known hardware issues,
as well as the latest available software, hardware documentation and design materials.
Always read the System Reference Manual!
3.1 Design materials
Design materials for creating your own customized version of the hardware,
or for better understanding the design are also linked from the traditional home of
"http://beagleboard.org/hardware/design"
BeagleBone Green hardware details
POWER button can be used to enter and exit hibernate modes once that feature is implemented
in the software.

3.2 Headers
The expansion headers provide extensive I/O capabilities.
3.2.1 Cape Expansion Headers
Each digital I/O pin has 8 different modes that can be selected, including GPIO.
3.2.2 65 Possible Digital I/Os
In GPIO mode, each digital I/O can produce interrupts.

3.2.3 PWMs and Timers
Up to 8 digital I/O pins can be configured with pulse-width modulators (PWM) to produce signals
to control motors or create pseudo analog voltage levels, without taking up any extra CPU cycles.
