The BeagleBone is a low-cost, high-expansion board from the BeagleBoard product line. It uses the TI AM3358/9 SoC based on an ARM Cortex-A8 processor core using the ARMv7-A architecture. It is similar in purpose to earlier BeagleBoards, and can be used either standalone or as a USB or Ethernet-connected expansion for a BeagleBoard or any other system. The BeagleBone is small even by BeagleBoard standards yet still provides much of the performance and capabilities of the larger BeagleBoards.
BeagleBone ships with a 4GB micro-SD card preloaded with the Angstrom ARM Linux distribution.
The board uses a TI TPS65217B PMIC to generate stable supply voltages regardless of input power variation. +5V DC power can be supplied to the BeagleBone through a barrel connector or from the mini-USB, both of which are located near the large RJ45 Ethernet connector.
The mini-USB type-A OTG/device client-mode socket is multi-functional. In addition to providing an alternative source of power, it gives access to an on-board front-end two-port USB client-side hub. (This is not related to the separate host-mode USB socket described later). One port of the hub goes directly to the USB0 port of the TI AM3358/9 SoC, while the other port connects to a dual-port FTDI FT2232H USB-to-serial converter to provide board-to-external-host serial communications and/or JTAG debugging. The BeagleBone's Linux serial console is available through this USB serial connection.
The SoC's USB0 connection to the front-end hub works in one of two modes, and you can toggle between them at any time: it either presents the SD card as a mountable USB storage device to the host, or it provides an Ethernet-over-USB networking interface which yields a simple method of quick-start. The Ethernet-over-USB facility is additional to the BeagleBone's normal 10/100 Ethernet interface, which is directly implemented in the SoC rather than hanging off USB as in some other designs. Full IPv4 and IPv6 networking is provided by the supplied Linux system out of the box.
In addition to the USB OTG Device or client-mode facilities already described, BeagleBone also provides one host-mode USB type-A socket on the other end of the board. This is driven from the USB1 connection on the AM3358/9 SoC, and provides access to USB host peripherals such as mice, keyboards, storage, and wifi or Bluetooth dongles, or a USB hub for further expansion.

Expansion Boards and Accessories
A BeagleBone Cape is an expansion board which can be plugged into the BeagleBone's two 46-ping dual row Expansion Headers and which in turns provides similar headers onto which further capes can be stacked. Up to four capes at a time can be stacked on top of a BeagleBone.
This section lists only those capes which are already available commercially or which are close to a production release.

BeagleBone Operating Systems
BeagleBone's default operating system is Angstrom, which ships with the board. This section provides basic information on Angstrom and other operating systems commonly used on BeagleBone.
- Home site: http://www.angstrom-distribution.org/
- Mailing lists: angstrom-distro-devel and angstrom-distro-users
- IRC channel: irc://irc.freenode.net/#angstrom
- Does not provide a forum, intentionally.
- Uses Busybox, which has both pros and cons. Advantages include requiring less storage space and a smaller memory footprint for many common utilities, which also improves system startup time and performance. The main disadvantages stem from those utilities not mirroring exactly their full-size counterparts. This may be annoying for some, and may also break shell scripts that rely on standard functionality.
- Uses connman for network connection management. No documentation is provided.
- Does not include man(1) nor any man pages by default, nor debugging utilities like strace(1) and tcpdump(1) which can be helpful in getting started.

Software development on the BeagleBone is normally no different to any other Linux platform, and typically varies with language and with the IDE used, if any. This section deals only with development issues that are specific to BeagleBone, or mostly so.
