9V LED Blinker PCB


I can’t run PCB analysis or auto-layout because no ACUs are currently available.
Current state:
  • The 9V NE555 LED-blinker schematic is complete with 11 through-hole components and 8 nets.
  • PCB placement and routing still require inspection; prior checks indicated unrouted airwires, so routing is needed and placement likely needs optimization first.
  • Exact MPNs remain unassigned for generic passives.
Once ACUs are available, the next operation is: inspect the board outline and existing placement, optimize through-hole component placement, route all nets, then run DRC and apply any necessary fixes.
I’m unable to analyze or auto-layout the PCB because the account has no available ACUs, so no project changes were applied.
Current project state:
  • The NE555 LED-blinker schematic is complete.
  • PCB placement still needs inspection/optimization.
  • The board has unrouted airwires, so trace routing is required.
  • After ACUs become available: inspect board/outline → auto-place as needed → auto-route → run DRC and apply fixes.
