Re...
software he wrote to upload the boot loader
For the innocent... is there an idiot's guide to how we do this somewhere?
Apart from the "coolness" factor of being slightly smaller than the RBBB... Oh! And the built in USB circuits, if you are going to be keeping it connected to a "big" PC (in which case why is being small good?) I don't see how this "beats" the less expensive (if you discount just a LITTLE of your time, for a quick and easy solder-up... which you can offset against the "upload the boot loader" chore) RBBB?
(Apologies if it seems I'm engaging in a "Mac vs PC" flame war... just interested in knowing the pros and cons. Yes, of course, I'm always delighted to learn that there's another alternative out there!)
