2023 Competition Electrical Architecture

Brief

The purpose of this document is to list out electronics (and their alternatives) that will be on the drone. The type of electronic is listed and then solutions (listed by higher probability of use first) with their requirements. Power consumption will be documented for flight time calculation as well as electrical power converter decisions. Weight, size, and sundry mounting requirements will also be noted to assist mechanical. Final mounting location will be decided by mechanical.
