\noindent It is extremely important to plug the battery in the correct direction into the volt meter as well, as plugging it in backwards (even for an instant) could damage the volt meter.
}

Using the Tamiya connectors, connect the battery to the switch and then the volt meter according to Figure \ref{sw sch}. Tye Tamiya connectors allow you to disconnect the battery from the rest of the system so you can recharge the battery.

\textbf{Note:} If you plan on using the LED matrix / face, you should split 5V power off of the 5V regulator before the Raspberry Pi, which should be done now. As the LED Matrix takes up a large number of GPIO pins which some might want for other devices, it's not a required part of the project and thus there is a separate document describing how to put it together.

\noindent To power the Raspberry Pi, we soldered the 5V and GND from the 5V regulator directly to the power pads on the bottom of the Raspberry Pi. The positive voltage goes to pad PP2 and negative/ground goes to pad PP5 in Figure \ref{rpi pads}. For more information and a video on doing this you can follow this link and go to around 3:30

NOTE: Before completing this section, you will need to populate the custom PCB boards that you received. Make sure you have completed all the custom PCB population and testing in the PCB Testing.pdf document before continuing with this document.

Figure \ref{rpi to rc} shows the schematic and pin-out of how to connect the Pi, Serial Splitter board, and Motor Controllers. From the Raspberry Pi we use the UART TX and RX pins, which correspond to pins \#8 and \#10, or GPIO14 and GPIO15. In addition we will be passing 5V to the motor controllers for the logic battery controller which is used by the encoders and digital logic. For this use the 5V PWR rail which is pin \#2 or \#4 and any of the GND pins (we recommend pin \#6). Raspberry Pi GPIO diagrams can be found on the following page in Figure \ref{RPi 3 pinout}.

\subsection{PCB - Logic Shifter Board}
\subsubsection{Overview/Schematic}
This board is made to handle the mismatch between the digital logic voltage level of the Raspberry Pi and the LED matrix. Digital logic is typically at either 3.3V or 5V. The GPIO pins on the Raspberry Pi will output at the 3.3V logic, and the LED matrix is made to read at 5V digital logic levels. In order to have these signals make sense to each other we use a device called a logic shifter, which will take the 3.3V signals and turn them into 5V signals.
