A hardware project usually moves through five stages: define what it must do, 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 commonly has a footprint, power, connectivity, or mechanical issue. Budget for two or three board revisions—that is normal hardware development, not failure.
Flux can substantially shorten design, checking, layout, and revision work, but it cannot eliminate fabrication and shipping time. A simple board may take days to a couple of weeks to design; complex power, RF, or high-speed boards can take several weeks. Each physical revision can then add roughly a couple of weeks for fabrication, assembly, and delivery, so manufacturing waits and debugging often dominate the calendar.
