LED Circuit Design Assistance

flux

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
