\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.

The "LOAD" terminals of the volt meter are the electrical load of the robot, which correspond to all the electronics running in the robot. Figure \ref{vm sch} shows the pin-out of how to connect the volt meter to the 5V regulator and the motor controllers.

\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}.

The corner motors only have the two connections to the physical motor, the (+) and (-) going to the top of the motor. However, you must also hook up the absolute encoder. When plugged into the encoder, the 3-pin Micro connector will have 3 wires coming out of it, shown in Figure \ref{3pin}.
