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.

Welcome to your new project. Imagine what you can build here.

Trying things out...

A buck boost converter that can be powered from a Li-ion battery and ouput 3.3V @500mA. Powered by the TPS63051YFFR and in the same package as a standard ADAFRUIT buck converter. Input Voltage Range: 2.5 to 5.5 Voltage.
