27
Project Modifications

• Main types of sensing are daughter boards rather
  than all on one motherboard
• Easier to break down piece by piece
• Easier to debug
• We have purchased power supplies rather than
  building themFor convenience
• Time constraints
• New allowance in budget

28
Project Modifications

• Ethernet is on a separate daughter boardAllows
  for easier debugging and block break down
• Looking into two different types of Zigbee
  wireless chipsAllows us to test to see which
  interfaces better
