Our goal when designing BreadBro was to combine two critical elements of the Open Hardware community: an Arduino and a solderless breadboard. To create almost any electronics project as a beginner, a breadboard is necessary, but it's rarely included with development boards. Starter kits usually include a separate breadboard, but then it becomes necessary to link the breadboard and Arduino using jumper wires. It can be flimsy and disorganized.
Our first attempt at this design involved providing wire rails to help organize projects. Ultimately, we found that it was more beneficial to integrate the Arduino and breadboard into a single unit.
The critical realization was the fact that, while a full-width breadboard wouldn't fit between an Arduino's header pins, a breadboard with one power bus removed would fit almost perfectly.
These failed attempts and simple realizations led to the current BreadBro design: A breadboard on top and a development board underneath.
BreadBro's electronics are protected from the work area by four rubber feet. This high-friction footing gives BreadBro some purchase on almost any surface, preventing it from sliding around as you build projects.
Many development boards, such as an Aruino Nano or Particle Photon, have footprints much smaller than BreadBro. These development boards are designed to be permanently employed in a project, or to be used with a breadboard. BreadBro gives you all the capability of an Arduino in the form factor of a breadboard!
Tomorrow we'll be looking more closely at one of BreadBro's prettiest feautures - its LEDs!
