Better Ground Plane
Optimized some traces to allow the ground plane to connect along the whole right side (SPI Flash side) of the circuit board.
All Traces Wired. Zero DRC Errors.
All traces ran. Zero DRC errors. Most of the DRC warnings can be ignored since they involve the LEDs and their footprints not including a certain layer or label.
V2 LED Matrix
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
