ATX Timer Power Board Design
0:00
Work completed
- Updated project description to reference external manual override header with hashtags: #PANEL_SW #Debounce #Override #CamMicroswitch
- Added debounce components:
- Added external header:
- PANEL_SW (2-pin)
- Made net connections:
- Removed on-board override switch:
- Deleted SW1
- Disconnected its pins from nets
- Severed SW1 nets:
- SW1:1 from +5VSB
- SW1:2 from CAM_PWR
Outstanding
- ERC/DRC checks and BOM review (cannot be run automatically)
Success criteria
- ✅ External 2-pin PANEL_SW toggles U5 latch via debounced CLK input
- ✅ On-board override button is removed
- ✅ Cam dial microswitch routing (+5VSB→CAM_PWR) remains untouched
- ⧗ ERC/DRC checks pending
Next step
Please run ERC and DRC checks manually to verify net integrity and pull-up behavior. Once they pass, we can proceed to schematic review and begin preparing the PCB layout (footprint review & stackup configuration).

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
