The Beagle Board is a low-power open-source hardware single-board computer produced by Texas Instruments in association with Digi-Key and Newark element 14. The BeagleBoard was also designed with open source software development in mind, and as a way of demonstrating the Texas Instrument’s OMAP 3530 system-on-a-chip. The board was developed by a small team of engineers as an educational board that could be used in colleges around the world to teach open source hardware and software capabilities. It is also sold to the public under the Creative Commons share-alike license. The board was designed using Cadence Or CAD for schematics and Cadence Allegro for PCB manufacturing; no simulation software was used.
