Just wanted to echo this problem. I’ve been trying to get a color LCD shield from sparkfun running on the Stalker but could not get the 3.3V required for operation. I was not even able to get 3 V on the pin when running from either a usb port, 9V battery, or a regulated power supply. Only by adding a secondary power supply did I get it to work. Power regulation seems to be a challenge. Any information that would fix this is appreciated.
