High-Current Spixels

by hzeller.

4 layer board of 2.52x2.21 inches (64.11x56.11 mm).
Shared on November 11th, 2017 21:32.

A Spixels board that provides higher current path to LED-strip connectors to be able to drive more LEDs directly. Ideally >= 2oz outer layers, 1oz inner layers, but OshPark only allows for half.

Power supply for Pi and LED power are separate, so that it is possible to drive LEDs on a different voltage or to reverse the voltage if CLK/DATA needs to be reversed. Provides jumper to connect the LED power to the Pi.
