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.
