I recently bought the Raspberry Pi and I have a few questions about the GPIO pins and power pins in general.
1. Is the voltage output TRULY 5 volts from the 5v pins? Forgive me if this is a stupid question. I hear it can vary?
2. What is the MAX current and voltage that can go back through the ground pin? Is the ground connected straight through back to the power supply?
Sorry if the questions are badly worded!
P.S feel free to move this to a different area - first post!
Thanks in advance!
