NEBULIX has produced an RBBB or Real Bare Bones Board — a complete, basic arduino on a small form factor PC board. These controllers are super convenient for embedded projects with space constraints, that don’t require shields or the full component count of the regular-sized boards.
“I had a bunch of Atmel ATMega-168 chips left over from a project so I did a run of RBBBs or Real Bare Bones Boards.” says NEBULIX creative director, Duncan McAllister. ” These tiny microcontrollers are great for embedded applications. I built a frequency counter with one.”
They’re just big enough to hold the chip, a crystal oscillator, a power regulator and reset switch. They breakout on the bottom in order to fit into a prototype board. These are also known as Boarduino for that reason. Great for prototyping when you don’t need a whole lot of onboard logic.
