Proffie BarBack

Proffie BarBack render:

The front is a standard 10-LED bar graph. The BarBack has four WS2811
chips on it, which drives the 10 LEDS. I’ll have to add some code to ProffieOS so that it will understand that these are 10 single-colored LEDs, and not four RGB leds though.

The pads on the left side are the inputs: -, data in, and + (the leg next to DIN is also where you connect the positive wire.
The pads on the right side let you connect to more pixels.
