I can’t execute design changes right now because there are no available ACUs for AI actions.
Current project state:
- New empty project created: Convincing Red Time Machine
- Components: 0
- Nets: 0
- No schematic or PCB work has been added yet.
Requested design intent captured:
- USB-powered LED lighting circuit
- GPIO-controlled ON/OFF from a microcontroller
- Constant-voltage LED drive
Recommended next design direction once ACUs are available:
- USB 5 V input with protection/filtering
- Logic-level MOSFET or load switch controlled by MCU GPIO
- LED supply rail driven from USB or regulated voltage depending on LED voltage/current
- Current-limiting resistors or LED module appropriate for constant-voltage operation
- Optional enable pull-down so LEDs stay OFF during MCU reset
To proceed later, I’ll need:
- LED voltage/current or LED strip/module part number
- MCU GPIO voltage: 3.3 V or 5 V
- Desired LED ON current / brightness
- Whether USB is USB-C or Micro-B / Type-A input
