“HVAC Mini Model with Variable Speed Control.”

flux

Your goal is to build an “HVAC Mini Model with Variable Speed Control”: power input + fan/blower drive (N-channel MOSFET low-side) + speed control input (knob or PWM) + optional thermostat/sensor interface, ending with a manufacturable PCB.
  • I’ve created a plan (status: ready_to_execute).
  • Next steps in the plan:
    1. Define architecture/requirements in the project description
    2. Build the full schematic (power entry, MOSFET motor drive, control input, optional sensor/thermostat, connectors)
    3. Set board outline/stackup, place connectors first, then place/route with separation of high-current vs signals
    4. Run DRC/manufacturability checks and export Gerbers/BOM/assembly outputs
Click Start on the plan bar to run it. Let me know if you want the control input to be potentiometer knob or external PWM (or both).
Use potentiometer knob
Use external PWM input
Support both inputs
Inspect current schematic
Check DRC/ERC now
