Another reduced size Arduino compatible board. Don’t know if it’s any cheaper than ModernDevice.com’s Really Bare Bones, the designer isn’t overly interested in starting a store. Design files are available so small runs for group projects or education can be organized via any online PCB service.
I like the ottantotto because it includes the serial interface, while the RBBB does not, but the availability and kit form of the RBBB has a lot going for it, particularly for my immediate concern of presenting a new project to a new audience.
