Questions!

Wow – its only been a couple of days since I posted the schematic and already a question. Basically its asking what voltage regulators am I using. My input power comes from a 7.4V pack of lipo batteries, usually about 300mAh capacity, I need 5V for my motor encoders, and 3.3V for the rest of [...]
