I can continue the design review and closure guidance here, but I can’t perform the remaining project-write steps from this interface.
The remaining work is the PCB mutation phase:
final layout inspect/setup confirmation
UI placement of connectors, switches, and holes
full route pass to eliminate airwires
final review and export
That matches Flux’s staged project-modification workflow, where placement/routing are separate layout actions after setup/annotation .
So the fastest path is:
Start the plan/execution flow in Flux
Run the remaining PCB stages in order:
inspect
ui-place
route
review/export
Then generate:
Gerbers
drill files
centroid
BOM
assembly drawing
testpoint map
Also, this thread is now quite long, so a fresh thread would likely make the next pass faster and more reliable; carrying forward key decisions is the recommended way to handle long-running design conversations .
If you want, I can do one of these next:
write a clean execution brief you can paste into a new thread to finish placement/routing fast
produce a release checklist for zero-airwire / manufacturing signoff
generate the exact final verification checklist for USB, TFT, buttons, audio, and test pads
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
Wirelessly connects power nets on schematic. Identical to the net portal, but with a power symbol. Used to organize schematics and separate functional blocks. To wirelessly connect power net portals, give them the same designator. #portal #power
