HARDWARE INTEGRATION PCB

Hardware Design

The hardware integration PCB was designed with two goals:

1. Minimize the footprint of the onboard electronics
2. Minimize the chances of wires disconnecting, during drives

To accomplish these goals,

The board consisted of n layers:

Technical Challenges

Design

  • Balancing priorities between HW design and getting a working prototype


Assembly

  • Wireless antenna connector on master board not accounted for in footprint, it may have to be removed to avoid interference with one connector.
