We finished the Preliminary Design Review Report and finished and presented the Preliminary Design Review Presentation to our sponsor and IPPD class. We designed a prototype layout for our PCB and printed it out to demonstrate where the pin mappings would line up with the chassis and the DSP board. We plan to make a chart documenting the pinouts between the DSP and the robot chassis and their compatibilities and review module 15 from the RSLK curriculum that covers audio signals!
