 You will need to attach male headers to the PCA9685 daughter board, as shown in figure 3.23. Also, 5v power is provided to the PCA9685 through the two holes at the top of the U2 header. To connect these, I soldered 2 small wire leads on the PCA9685 daughter board, and then soldered them on to the motor board once I installed the PCA9685.

 Before we insert the wiring and PCBs into the mechanical assemblies, we'll test and configure the drive motors, wiring, and PCB. This allows us to fix these critical parts if something doesn't look right and allows us to move to running the software as soon as the rover is assembled.
