Powering through GPIO pins
Forums:
This is my first foray into robotics and really the raspberry pi in general. When everything is connected, the Raspberry pi is getting power through the source being supplied to the thunderborg via the 5v GPIO pins. The batteries running into the thunderborg are a series of 4 7.4v batteries. I'm pretty sure this is way too much power to go into the pi through the pins, since they are rated for 5v. I'm just wondering if I missed something and connected it wrong, or if this should be what's happening.

bad wording
I just realized the explanation is worded pretty badly. Essentially I am powering the thunderborg with a series of batteries. I am then connecting the thunderborg to the Pi via the gpio pins, but the Pi ends up getting power from the batteries connected to the thunderborg. This seems like it's an issue since the voltage rating is much higher than what those pins should be taking.

ThunderBorg powering Raspberry Pi
Nothing to worry about, this is how the ThunderBorg is supposed to work :)
ThunderBorg has an on-board voltage regulator which takes the battery voltage and reduces it to a steady 5V. This 5V is then used to power the on-board logic, LED, and the Raspberry Pi via the GPIO connection.
