BeagleBoard: A Compact and Powerful Single-Board Computer

Introduction

BeagleBoard is an open-source, low-power single-board computer (SBC) developed by Texas Instruments in collaboration with Digi-Key and Newark element14. It was designed to demonstrate the capabilities of TI's OMAP3530 system-on-a-chip (SoC) and to support open-source software development. The BeagleBoard is widely used in education, embedded systems, robotics, and IoT applications.

Key Features of BeagleBoard

1. Processor: ARM Cortex-A8 (600 MHz - 1 GHz)
2. Memory: 128 MB - 512 MB RAM
3. Storage: Supports SD/MMC cards; some models include onboard NAND flash
4. Connectivity: USB On-The-Go, RS-232 serial, JTAG debugging
5. Ports:
• Video: HDMI, DVI-D, S-Video
• Audio: 3.5mm stereo jacks
• USB: USB OTG and USB host ports
6. Power Consumption: Low power (~2W)
7. Size & Weight: ~7.62 cm x 7.62 cm, ~37g

Development & Use Cases

• Operating System Support:
  BeagleBoard supports multiple OS options, including:
• Linux distributions: Ubuntu, Debian, Fedora, Angstrom, Arch Linux
• Other OS: FreeBSD, OpenBSD, Android, Windows CE, RISC OS, QNX
• Programming & Development:
• Used for embedded programming, IoT, robotics, and AI applications.
• Supports Python, C/C++, Java, and other languages.
• Educational Purpose:
• Commonly used in colleges and universities for teaching open-source hardware and software development.

BeagleBoard Variants

Several variants of the BeagleBoard have been introduced over time with improved specifications:

1. BeagleBoard-xM (2010)

• Upgraded CPU (1 GHz) and RAM (512 MB)
• Onboard Ethernet and 4 USB ports
• Lacks NAND flash, requiring boot from an SD card

4. BeagleBoard-X15 (2015)

• Dual-core ARM Cortex-A15 processor (1.5 GHz)
• 2 GB RAM, USB 3.0, HDMI, Gigabit Ethernet
• Designed for high-performance applications

5. PocketBeagle (2017)

• Ultra-compact version (~50% smaller than BeagleBone Black)
• Reduced cost and weight
• Designed for embedded systems and robotics

Comparison with Raspberry Pi

Conclusion

BeagleBoard and its variants are powerful, low-cost single-board computers that offer great flexibility for embedded development, robotics, and education. While Raspberry Pi is more popular for general computing and beginner projects, BeagleBoard provides better expandability, industrial-grade support, and open-source hardware advantages.
