Beaglebone Black Power Jack Size
The default graphical user interface (GUI) used for the BeagleBone Black is LXDE, which stands for lightweight X11 desktop environment. It’s part of the Debian Wheezy distribution, and it’s one of the best solutions for the BeagleBone Black because it’s optimized for processor and memory use. It’s a lightweight GUI.

The BeagleBone has two USB ports, a full sized USB-A port, and a mini-USB port. The mini port is located on the reverse side of the board near the Ethernet jack. The board should boot and you should see a solid blue light next to the 5V power jack. When startup is completed, a new mass storage device called BEAGLEBONE should appear on your desktop. Power the BeagleBone Black down and locate the 'User Boot' button. It's located on the top side of the board, directly above the micro SD card slot which is located on the reverse side along with the mini and micro USB sockets. The BeagleBone Black will try to boot the internal Angstrom image by default.
The Original BeagleBone doesn’t support an HDMI output. If you purchase an LCD cape for your Original BeagleBone, however, the desktop environment is exactly the same as shown here, so you can easily follow along.
Most peripherals and cables are pretty standard. You may already have most of them, and those that you don’t have are easy to acquire. You may need the following list of components:
Micro HDMI cable
USB hub
Keyboard and mouse
Ethernet cable
Power adapter
This figure shows where you connect each of the peripherals on the BeagleBone Black.

You need to have installed the latest image of the Debian operating system in your BeagleBone Black’s eMMC memory or on a microSD card that’s inserted into your BeagleBone.
Make sure that your BeagleBone Black is properly updated and upgraded. It’s a good idea to connect to it through Secure Shell (SSH) and run the following on the command line:
Connecting a Micro HDMI cable or DVI display
HDMI (High-Definition Multimedia Interface) displays have replaced DVI (Digital Visual Interface) displays. Although many DVI displays are still being used for many applications, the trend has been to shift to HDMI. The BeagleBone supports only Micro HDMI output, but if you have an adapter that can convert DVI to HDMI, you can repurpose an old DVI display. If you have an active HDMI converter, make sure that it has an external power source.
Use a Micro HDMI cable with an HDMI display. Some DVI displays won’t be compatible with your BeagleBone Black, and ultimately, a DVI display may not display anything in your screen. You could spend a lot of time trying to figure out the problem, only to realize that the screen you used isn’t compatible with your BeagleBone Black.
Connecting a USB hub, keyboard, and mouse
Because the BeagleBone Black offers only one USB host slot, you must use a USB hub to plug in more than a single USB peripheral. You can get an inexpensive hub like the one shown here at most electronics or computer stores. To use the BeagleBone Black as a desktop computer, you need to connect a USB keyboard and mouse to it.
Connecting to your router
Do you ever wonder whether it’s still possible to use a computer without an Internet connection? You can simply connect an Ethernet cable from your home router to the BeagleBone Black. After you’ve made that connection, you can easily install and update software or simply browse the web while using your BeagleBone Black as a desktop computer.
Connecting the power
Connecting both a mouse and a keyboard to the BeagleBone Black can be quite power-consuming, so the power provided by an USB cable may not be sufficient for everything to work smoothly. If you connect your BeagleBone Black via USB to your desktop or laptop computer and everything lights up, great! The BeagleBone Black is getting power.
Some functions may be slow or won’t work properly, however. In the worst-case scenario, the peripherals may not even light up. To err on the side of caution, you should get a proper power adapter. That way, you can rest assured that your BeagleBone has all the energy necessary to run at its fullest speed and performance.
Make sure your power adapter provides 5V — not more or less than that! Also, you need to ensure that the power adapter has the correct polarity on the jack: The center provides 5V, whereas the outer ring is ground (GND).
Booting up
As soon as you apply power to your BeagleBone Black, it automatically boots. After a few seconds, you should see the typical, awesome-looking beagle with its tongue sticking out as the background of the desktop.
If you don’t see anything on the display, try disconnecting everything and then redoing the connections described previously. Then reboot your board. Also, if you’re using a TV set as your display, make sure that you change its source to HDMI.
If you can’t see the full image shown, or if it’s small in comparison with the screen, the problem has to do with your screen’s adjustment. Try going into your screen’s settings menu and adjusting the picture size until everything fits in a way that’s pleasant to you.

With a variety of different single board computers, it can be difficult to choose which is right for your project. This article will look at the basics of three single board computers available.
BeagleBone vs. Raspberry Pi vs. Tinker Board
In this article, we'll look at three single board computers: the BeagleBoard BBWL-SC-562 Raspberry Pi 3 IBM-IOT Kit, and the ASUS Tinker Board. As a bonus, we'll also take a quick look at the Raspberry Pi Compute 3 Kit.
BeagleBone Black BBBWL-SC-562
The BeagleBone computer works well for maker-like environments where open-source hardware is essential. Although it contains less memory and lower speed than the other single board computers on the list, it makes up for it with its small credit card size and a large number of GPIO provided in the form of 92 pins.
Also included is onboard 4GB of flash storage (whereas most other machines require the use of an extra SD card) which allows the unit to run many Linux distros out of the box. The BeagleBone Black also includes two power options from either a 5V DC jack connector or a micro-USB connector.

- Compatible with Debian, Android, and Ubuntu
Raspberry Pi 3
The Raspberry Pi computer series has been the center of the single-board computer explosion, which has seen three revisions of the Pi. The IBM-IOT kit comes with the Raspberry Pi 3 which is a rather powerful computer containing a 1.2GHz 64-bit quad-core ARMv8 CPU, 1GB RAM, and plenty of peripherals.
The Raspberry Pi is suited for computer-oriented projects which require more processing power, multiple USB devices, and inbuilt Wi-Fi capabilities. For example, the Raspberry Pi would be ideal in many IoT projects that involve displays and keyboards such as user interfaces, control stations, and home automation.

ASUS Tinker Board
ASUS released the Tinker Board in January of this year, ostensibly to compete with the Raspberry Pi. By some measures, the Tinker Board is actually more powerful than the Raspberry Pi 3, particularly in the areas of graphics and sound.
The key to that is that the Tinker Board has a powerful SoC. The Tinker Board has an ARM processor, like the RPi 3, but differs in that it uses a Cortex-A17 1.8GHz model rather than a Cortex-A53 1.2GHz model. It also has twice the memory when compared to the RPi 3, 2GB of LPDDR3 DRAM rather than 1GB of LPDDR2 (a previous generation of mobile DDR memory).

One of the downsides of the Tinker Board is that it doesn't have a robust system of support (yet). Part of this problem is that it's comparatively new to the scene (and therefore can't hope to compete with the community behind the Raspberry Pi). But there's also a marked lack of official support offered by ASUS that can be problematic. This isn't dissimilar from the troubles engineers and makers had with Intel's (now canned) Edison SBC, which was notorious for its lack of documentation and support.
Features
- Rockchip Quad-Core RK3288 processor (max resolution: 4K@30hz with H.264/H.265 hardware encoder)
- 2GB Dual Channel DDR3
- Integrated ARM Mali-T764 GPU
- Micro SD(TF) storage
- RTL GB LAN
- 802.11 b/g/n, Bluetooth 4.0 + EDR
- Four USB 2.0 ports
- 40-pin GPIO
Bonus: Raspberry Pi Compute 3
Beaglebone Black Wireless
Not all projects require the use of a graphics engine and USB ports. This is where the Compute 3 module comes in. The Compute 3 comes with a rather powerful processor (as compared to microcontrollers such as those in the PIC, AVR, and ST), plenty of IO in the form of IO pins but no peripherals, making it ideal for industrial automation environments.
The Compute 3 module is a cheaper and smaller version of the Raspberry Pi which also makes it useful in applications where space is a virtue. Some example applications for the Compute 3 module would include remote locations (such as drones, rovers, and possibly high-altitude weather balloons), factory environments (such as robotics), and home automation where only computing power is needed.

Features
- BCM2837 Processor up to 1.2GHz
- 1GB RAM
- 4GB onboard flash
- Packaged in a DDR2 SODIMM PCB (useful for pre-existing sockets)
- Largely backward compatible with Compute 1
Summary
Depending on the project, different single board computers will be the most effective. With each project, it pays off to take time considering which module you should use.
