Building hardware typically goes through: define the product, shape the enclosure and interfaces, design the schematic, lay out the PCB, manufacture and assemble it, then bring it up and debug it. The key expectation is iteration: Rev 1 usually reveals issues—a footprint mismatch, power problem, or missing connection—so budgeting for 2–3 board revisions is normal, not failure.

A simple board may take days to a couple of weeks to design; RF, high-speed, or multi-rail designs can take several weeks. Each physical revision can add roughly a couple of weeks for fabrication, assembly, and shipping. Flux can accelerate design and revisions, but not those manufacturing waits. No project changes were made in this session; execution stopped because your ACUs ran out.
