R2-D2 seems to run on 3 voltages:

• 6V for the motors
• 4.5V for the logic
• 1.5V for clock or memory keeping

From other projects I've learned about drone parts, known as BECs that convert LiPo voltages to 5V and most often 12V. I want to modify the HTPDB-XT60 module so it will convert to 5V and 6V instead, so I can use a 2-cell LiPo pack.

To control the motors I will use a DRV8838 single motor driver for the dome and a DRV8833 dual driver for the leg wheels
