So I have been playing with the Pi for quite a bit, both the Model B and now the Pi 2. Since the Pi 2 came out I had fed it with a 12v 2A power supply dropped through a module very much like this one ( http://www.ebay.com/itm/5V-USB-Converte ... 0813369212 ). It worked, but I always had the red LED blinking if I had the Pi Camera and wifi hooked to the Pi. So checked it out and I was getting a voltage of only 4.7-4.8v out the Pi usb ports. I was using a Monoprice 24/28awg 3' cable at the time. Eveything worked with only a couple lockups over the past year.
Last night I upgraded the voltage reg to this one; http://www.ebay.com/itm/221921225118?_t ... EBIDX%3AIT Placing a meter on the USB port of the pi as well as monitoring the readout on the new regulator I proceeded to increase the voltage until I got 5.0v out of the usb ports on the pi and the red LED would no longer flash when I ran my hand infront of the camera (causing motion detect to fire and start recording video over the wifi to my server). The final output on the regulator now reads 5.4v. The Pi reads a nice 5.0-5.03 volts on its usb output. I plan on moving the PS to close proximity and shorten the cable drastically to a few inches but before I did that I wanted to ask, should I stick to the micoroUsb connector or go to GPIO or ..?
