WS2813 hack connector

WS2813 connector with power MOSFET and level shifter hack

• No level shifter IC needed to run Neopixels/WS2812/WS2813 from 3.3V microcontroller
• MOSFET to turn LED strip power on/off from a microcontroller GPIO pin

A SMD version of the WS2813 gets sacrificed to run at ~4.3V (powered through the diode), which makes it accept 3.3V data signals. The data signal it outputs can then be used to control WS2812/WS2813 LEDs running at 5V. 

Pins:

• DIN: Connect directly to microcontroller GPIO (data pin)
• FET: Connect directly to microcontroller GPIO (turn MOSFET on/off)
• DO: Connect to WS2812/WS2813 DIN pin
• LGND: Connect to LED strip GND
• 5V: Connect to LED strip 5V
