    On Air R2 - Thread Enabled

    On Air R2 - Thread Enabled thumbnail
    R2 w Thread changes: -Moving to Letter Modules for ease of design -Adding MGM210L for Matter on Thread On/Off and intensity control -Shifted A and R letters closer to fix Kerning
    -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 #arduino-matter
