Electronics and Robotics Developers Choice: Beaglebone Black

Developers, makers, and hobbyists looking for a better alternative to Raspberry Pi. Now has taken the wraps off a 1 GHz ARM-based board named the BeagleBone Black (BBB).  You can use it as a Computer, Media Center, or the controller of your Robotic Project.  One of the features that I am crazy about is the presents of ADC, PWM and lot of GPIO. As a Electronics and  robotic developer, I like Beaglebone Black and is a wonderful choice!!!!

The 3.4 x 2.1 in (8.6 x 5.3 cm) BeagleBone Black open-source Linux computer comes pre-loaded with the Ångström distro (which will  boot in under 10 seconds) and Cloud9 IDE, freeing up the microSD slot for additional storage. It's based on the Sitara 1 GHz ARM Cortex-A8 processor from Texas Instruments, including a 3D graphics accelerator. There's 2 GB of integrated eMMC flash storage and 512 MB of DDR3 RAM.  HDMI monitor, Keyboard and mouse is not must for a developer, Straight away you can connect BBB to your PC and start Development ( Now it will act like an Arduino). If you connect a Monitor, keyboard and mouse you can use it as a standalone PC.

Cost : $45 (Indian Price Approx. Rs.3200 + Shiping)

Processor: AM335x 1GHz ARM® Cortex-A8

  • 3D graphics accelerator
  • NEON floating-point accelerator
  • 2x PRU 32-bit microcontrollers


  • USB client for power & debug
  • USB host
