Hi! Based on your description, your approach should be compliant. As long as the PCB is only manufactured and delivered before the hackathon, without any testing, coding, or activation prior to August 1. it aligns with the rule prohibiting early development. Passive preparation (like fabrication) is typically allowed, especially when it's necessary for logistics.
You’ve clearly directed the design for this specific hackathon and are not beginning any functional work ahead of time. Still, for full clarity, I’d recommend confirming with the hackathon organizers directly.
Good luck at TechXchange 2025!
