LED Module redesign with the intention to install the PCB into an official Framework LED Matrix plastic housing.

Changes for V2:

  • 5 volt input polyfuse
  • 3.3 volt input polyfuse
  • 300 to 500 Ohm resistor between the data pin of the first led in a strip and the level shifter. From: https://learn.adafruit.com/adafruit-neopixel-uberguide/basic-connections
  • Change level shifters to use this cheaper chip: 74AHCT125
  • Change LED topology. Limit to 8 strips of LEDs
  • Change which digital pins the 8 strips are connected to so they are use sequentially numbered digital pins. That way it will work with NeoPLX8 (https://github.com/adafruit/Adafruit_CircuitPython_NeoPxl8).
  • Added pads on so that all 8 strips could be connected into one series array
  • Bigger pin assignment silk screen text on the back
  • [Maybe] Mounting holes for diffuser grid
