BeagleBone Green Wireless
Introduction
SeeedStudio BeagleBone Green Wireless (BBGW) is a joint effort by BeagleBoard.org and
Seeed Studio. It is based on the open-source hardware design of BeagleBone Black and
developed into this differentiated version. SeeedStudio BeagleBone Green Wireless has included
a high-performance flexible WiFi/Bluetooth interface and two Grove connectors, making it
easier to connect to the large family of Grove sensors. The on-board HDMI and Ethernet are
removed to make room for these wireless features and Grove connectors.

Hardware Overview

Pin map
Each digital I/O pin has 8 different modes that can be selected, including GPIO.
65 Possible Digital I/Os
Note
In GPIO mode, each digital I/O can produce interrupts.

PWMs and Timers
Note
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
Note
Make sure you don’t input more than 1.8V to the analog input pins. This is a single 12-bit
analog-to-digital converter with 8 channels, 7 of which are made available on the headers.

UART
Note
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.

I2C
Note
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.

SPI
Note
For shifting out data fast, you might consider using one of the SPI ports.
Getting Started
Note
This chapter is writing under Win10. The steps are familiar for the other operate systems.
STEP1. Plug in your BBGW via USB
