MicroSD/MMC card is also used for storing the data. For audio, it has Stereo in and out jacks. For powering the device it has Power socket (5 V barrel connector type). BeagleBoard-xM is provided with the separate camera port.

  • Beaglebone Black:

Beaglebone black is a single board computer.it is most commonly used. For storage, it uses 512MB DDR3 RAM and 4GB 8-bit eMMC onboard flash storage. It has 3D graphics accelerator for better performance of CPU.NEON floating-point accelerator. Beaglebone black has 2x PRU 32-bit microcontrollers. It has 3 I2c buses for serial communication. CAN and Spi bus for communication. It has 4 timers and 65 GPIO pins. Beaglebone black has seven analog inputs used 1.8v max 12 bit A/D converters.

  • BeagleBone Blue:

BeagleBoneBlue is an all-in-one Linux-based computer for robotics, integrating onto a single small (3.5″ x 2.15″) board the Octavo OSD3358 microprocessor. It has both wifi and Bluetooth for connectivity, IMU/barometer, power regulation and state-of-charge LEDs for a 2-cell LiPo, H-Bridges, and discrete connectors for 4 DC motors and encoders.it also having 8 servos, and it has all of the commonly-needed buses for additional peripherals in embedded applications. Beaglebone blue is open source and actively supported by a strong community, the real-time performance, flexible networking, and rich set of robotics-oriented capabilities make building mobile robots with the Blue fast and streamlined.it has AM335x 1GHz ARM® Cortex-A8 processor and for internal storage memory its with 512MB DDR3 RAM and with 4GB 8-bit eMMC flash storage. It has integrated power management. Majorly 2×32-bit 200-MHz programmable real-time units (PRUs) and neon floating-point accelerator. Beaglebone uses ARM Cortex-M3 processor.for the purpose of power and communication it has USB2 client. This uses 2-cell LiPo with balancing, LED state-of-charge monitor as a battery. For Charging it needs input upto 9-18V.it having Wireless connectivity 802.11bgn, Bluetooth 4.1 and BLE. For Motor control of 8servos, it has eight 6V servo out, 4 bidirectional DC motor out, 4 quadrature encoder. It has 9 axis IMU sensors (accels, gyros, magneto meter), barometer, thermometer. Beaglebone has 11 user programmable LEDs, 2 user programmable buttons for the user interface. It also having additional buses and peripherals including GPS, DSM2 radio.

  • BeagleBone Green:

BeagleBone Green (BBG) 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. The BBG has included two Grove connectors, making it easier to connect to the large family of Grove sensors. On-board HDMI is removed to make room for these Grove connectors. BeagleBone Green uses the AM335x 1GHz ARM® Cortex-A8 processor. For storage, it has 512MB DDR3 RAM and 4GB   8-bit eMMC on-board flash storage. It has a graphics board called3D graphics accelerator for having better performance of like CPU. It has

NEON floating-point accelerator to improve the multimedia user experience. It also has 2x PRU 32-bit microcontrollers.

  • BeagleBoard-X15:

The BeagleBoard-X15 is based on the TI Sitara AM5728 processor with two ARM Cortex-A15. Its core running at 1.5 GHz, two ARM Cortex-M4 cores running at 212 MHz and two TI C66x DSP core running at 700 MHz. This processor provides USB 3.0 support and has a PowerVR Dual Core SGX544 GPU running at 532 MHz.

  • Pocket Beagle:

Pocket beagle is launched in September 2017. Pocket Beagle offers identical computing performance to BeagleBone Black in a physical form factor that offers over 50% reduction in size and 75% reduction in weight. This model is cost effective than the above models. The miniaturization was made possible by using the Octavo Systems OSD3358-SM that shrinks all major subsystems of the BeagleBone Black into a single ceramic package attached using a ball grid array. This advantages of the miniaturization come at the cost of removal of all built-in connectors except for a single micro USB port, the removal of on-board eMMC flash storage, and a reduction of header pins from 92 down to 72 due to space constraints, meaning that most capes will either not work at all or need heavy modifications to work with Pocket Beagle.  Pocket Beagle include embedded devices where size and weight considerations are most critical, such as quadcopter drones and other miniaturized robotics, along with handheld gaming applications.

Languages to code Beaglebone:

Can write our code in almost any language like C, C++, Python, Perl, Ruby, Java, or even a shell script.

Linux software: Much of the Linux software that’s already out there can be run on the BeagleBone

Software capability:

Beaglebone can be used in Debian platform, Android. Can  run Ubuntu linux distribution on Beaglebone black  and Cloud9 IDE on Node.js w/ BoneScript library can be used.
