ESP32 DC Load Controller Design

Your goal is to turn this ESP32 reference design into a compact 24 V DC PWM load controller with the interfaces and sensing you listed.
  • I’ve created the plan to:
    1. Update power for 24 V input and ESP32 regulation
    2. Add BTF3050TEATMA1 PWM load drivers and screw terminals
    3. Add JST switch, sensor, and conditioned analog inputs
    4. Add Qwiic OLED and compact layout constraints

You want to proceed with the plan for the compact 24 V ESP32 PWM load controller.
  • The plan is ready to execute.
  • Click Start on the plan bar to begin the work.
  • If you want, I can still revise it before execution, for example:
    • number of PWM outputs
    • number of analog inputs
    • exact JST/screw connector preferences
Add input protection
Specify output count
Define analog channels
