Comparing the 3DoT Board to the Latest Hardware

The 3DoT Board is difficult to compare, as there are not many boards specifically designed for robots. The most common solution is to use a Raspberry Pi or an Arduino with add-on components called “breakout boards”, or “shields”, to build a system capable of controlling a robot. If you need a ton of processing power or other specialized features, this may be the way to go, but we don’t think most robots need this.
