IF I had to add a regulator, I would use one like this: https://www.adafruit.com/products/1066
They are more efficient than the 780x generic regulators, and they are smaller too. Great little project, I hope to get a few.
Those step-down regulators are great, very efficient.
The problem with the 78xx is that they emit heat, i.e. waste energy, approximately in amount of the voltage & current that is above the limit set by the circuit – that’s how they work.
I’m not very familiar with the MCP1700 mentioned in the comment below.
The idea is that if you need a voltage regulator you probably already have additional components and maybe a shield-like board on top of the Tinusaur board, so that should be the proper place to put a voltage regulator.
Hey, we have just launched our first Indiegogo crowdfunding campaign at http://igg.me/at/tinusaur that will help us build more of those awesome boards. Please, support us if you can and wish us luck!
