On Air R2 Demo

On Air R2 Demo thumbnail
R2 changes: -Moving to Letter Modules for ease of design -Adding ESP32 for WiFi On/Off and intensity control
-Optional: Add unpopulated AA Battery Holder for battery option
R1 changes: -Changed LED part to Red LEDs -adjusted resistor value of buck converter -Changed source for USB-C Connector -Removed exposed soldermask on buck converter with negative soldermask expansion -Order with black soldermask
Modified by markwu2001:
  • Adjustable Brightness,
  • 85-90% Drive Efficiency
  • <5W Operation (Can use 5V 1A Plug) This project can be purchased from LCSC
Original Description: Daddy's second circuit board. A sign to let my wife know when I'm on a call. Activates with a slide switch and is powered by USB-C. #template
