Beaglebone Black is a no less than a computer. Yes, you read it right. It is packed with everything you find in a desktop or a laptop. A powerful processor, memory, and graphics acceleration all shrunken down as chips and soldered into a single circuit board. Therefore, it is fair enough to call it a single-board computer.

This powerful microcontroller board can be hooked up with a display, speakers, Ethernet network, keyboard and mouse. Moreover, it can be used to boot up a LINUX operating system.

It is a powerful tool for hobbyists and researchers to build sophisticated projects and a good approach to learning more about LINUX based operating systems.

Beaglebone Black Pin Configuration

Each digital I/O pin has 8 different modes to choose from, including GPIO.

Below are the BeagleBone Black Pinout tables for the P8 and P9 expansion headers of the Beaglebone black.

The PROC column is the pin number on the processor.

The MODE columns are the different mode setting available for each pin.

Please note that the MODE5  is missing because it really just don’t do anything. The only pin that works in MODE5 is GPIO0_7 in expansion header P9. It can be set as mmc0_swdp.

  • Up to 8, I/O pins can be configured  with PWM (pulse width modulator) to generate signals to control motors without taking up any extra CPU cycle
  • Pin number (32-40) in header P9 constitutes a single 12-bit analog to digital converter having 8 channels
  • There are two I2C ports. The first I2C bus is utilized to read EEPROMS. It can also be used for another digital I/O operations without interfering with that function. The second I2C is available to configure according to the need of the user
  • There are 2 SPI ports for fast shifting of data
  • For advanced users, the Beaglebone black consists of 25 PRU low latency I/Os. They can make use 2 built-in 32 bit 200 MHz microcontrollers called PRU (Programmable Real-time Unit) in order to perform some real-time task

Where is Beaglebone black used?

The Beaglebone Black is a pocket-friendly, compact development platform with excellent support from its fast growing community. It is a perfect device for physical computing and smaller embedded applications.

The best feature of Beaglebone black which makes is it a complete game changer is the feature to add different capes to it. Capes are plug-in boards which are added to Beaglebone black to enhance its functionality. Capes are available for motor control, VGA, camera, LCD, and other functionalities.

The Beaglebone Black can be used when –

  • When you need to run heavy operating systems with low power

 There are many scenarios during a DIY project when Arduino is not enough. For example, during the boot of operating system and running heavy softwares, Arduino will require extra power. Here, Black comes in handy and does the same operation with low power.

  • When your project needs a lot of hardware to connected.

In terms of GPIO connectivity, the Beaglebone black knocks out Raspberry Pi. In Pi, we have a single 26-pin header to be used as 8 GPIO pins or serial bus. However, in Beaglebone black, we can find two 48-socket headers using which we can connect virtually n number of I/O hardware. It also features a number of analog I/O pins to connect sensors which out-of-the-box Pi lacks.

  • When you want your project to start quickly

Beaglebone black takes very less time to get up and running. It comes with pre-installed LINUX distro which saves a lot of time and prevents fuss.


How to get started with Beaglebone Black?

As mentioned earlier also, that getting started with Beaglebone black is a very quick and easy process.

  • First, plug-in it into your computer using the included mini USB. This will power it up and boot into its LINUX distro, Angstrom
  • Hook it up to a display and USB peripherals
  • You can intall driver to connect Beaglebone black to web browser an dcontrol it with your computer
  • From here, there are no limits. You can get acquainted with the LINUX operating system or write custom softwares for Beaglebone black using Python and libraries to manage all GPIOs



  • Robotics
  • Motor controller
  • Controlling and monitoring using Display cape
  • Automation
  • IOT
  • AWS
  • Bluetooth connectivity projects
