Speed Controllers
• How do you choose?
• Linearity (great for drive train, possibly not needed for other items)
• Size (smaller is always better)
• Control (direct sensor feedback can be very useful)
• What do you have in stock?

Board Layout • How do we lay out our board?
• List all items on board and get all of them
• How much room you have for board?
• Where does the board go?
• Spacial constraints
• Lay out all components and their wire routes to make sure they all make sense
