I've just released two new prototyping boards for the RBBB and Boarduino: Wicked Device Shop
I have always liked these boards as a concept, but have been frustrated that you can't easily use them for semi-permanent prototyping, and you can't use them with regular Arduino shields. Both these problems are now solved. They use long pin headers, so you can mount shields on the top and/or the bottom of the proto-shield.
I was just looking at your photo again, and I notice something.
Your RBBB does not look like my RBBB, and if they really are different, my RBBB would not fit this board, as the pin lines are narrower.
Mine is RevB, the pin lines are 0.600 wide.
Have you checked this using the latest RBBB version from ModernDevice???
@OrbitalAir: You are correct. The image above shows the BoArduino version. This would not fit an RBBB. The size and pinouts are different, and require different boards. We have a versions for both the BoArduino and RBBB.
