Hmmm -- these do look tasty -- I'm afraid that the ymight be just a tad too wide - -I need to get my hands on one to check it out -- I'll order one today (the other thing is the cost -- remember tha tI need 250 of these little scamps)
Just to give you a taste of what's to come, one of the things I want to do is run my Arduino Mega, chipKIT Max32, and all of the LEDs in the BADASS display off a common 26A 5V highly-regulated supply.
However, the Arduino Mega requires a minimum of 7V (and preferably 9V or higher) from it's external supply. Meanwhile, the chipKIT Max32 does have the ability to bypass the main regulator and feed the 5V in directly, but there is a teeny-tiny gotcha if you also have the USB cable connected to a computer at the same time.
Fortunately, my on-site techno-weenie Ivan the Terrible (author of the "All About Batteries" blogs here on EE Times) has come up with cunning solutions to all of these issues.
