Over seven months, Lee Shapira developed and refined avionics hardware and embedded software for the Terrapin-Rocket-Team/SRAD-Avionics repository, focusing on power delivery, radio communication, and sensor integration. He designed and optimized PCB layouts using KiCad, implemented low-power modules, and integrated USB-C and 4GFSK radio configurations to improve system reliability and test coverage. Lee’s work included schematic capture, state machine logic in C/C++, and configuration management to streamline manufacturing and validation. His approach emphasized traceable commits, manufacturability, and robust testing, resulting in a well-documented, production-ready hardware platform with enhanced telemetry, operator feedback, and maintainable code and hardware artifacts.
