So for the project I am working on I am attempting to power a Raspiberry Pi 3 through the 5V Pin along the header. This is the setup I have:
The large orange box on the right is a 12V power supply, which runs through a 7805SR-C Voltage Regulator(circled in red) to supply a 5V output to power the Pi.
My problem right now is that when attempting to power up the unit it gets stuck booting. Basically it will start to boot, get to one point, and shut down and start booting again. I'm sure this is because it isn't getting enough power (positive in fact, I was having the little "Not enough power" lightning bolt showing on my monitor) which may be due to the voltage regulators only outputting at 500mA.
As you can see, I have two voltage regulators set up. Currently I have nothing running from the 5V output of the second one. Would I be able to hook up the other 5V Pin to the other regulator without essentially blowing up the Pi?
I'm not exactly electrical savvy, I was kind of just handed this and told, "make it work" :|
I'm unsure if the extra voltage will be too much for the Pi or if it will be fine because of the low current from the regulators.
Thanks for your time.
