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.
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! 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...
Headers The expansion headers provide extensive I/O capabilities. Cape Expansion Headers 3.2.1 Each digital I/O pin has 8 different modes that can be selected, including GPIO. 65 Possible Digital I/Os 3.2.2 In GPIO mode, each digital I/O can produce interrupts.
PWMs and Timers 3.2.3 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.
Analog Inputs 3.2.4 analog- Make sure you don't input more than 1.8V to the analog input pins. This is a single 12-bit to-digital converter with 8 channels, 7 of which are made available on the headers. 3.2.5 UART There is a dedicated header for getting to the UART0 pins and connecting a debug cable. Five additional serial ports are brought to the expansion headers, but one of them only has a single direction brought to the headers.
3.2.6 The first I2C bus is utilized for reading EEPROMS on cape add-on boards and can't be used for other digital I/O operations without interfering with that function, but you can still use it to add other I2C devices at available addresses. The second I2C bus is available for you to configure and use.
