Description:

Display with two 8x8 matrices of multi-colour Neopixel RGB LEDs.

OLED display can be used for scoring, etc.

Features:

- 1000uF surge caps for RGB Neopixel LEDs

- Each RGB LED has its own decoupling cap

- 3v3/5v level shifter for data signal to RGB boards

- Amplified buzzer speaker

Details:

-Two matrices of  64 Neopixel RGB LEDs (RGB board) are arranged in an 8x8 matrix

- Pressing the GO button causes the matrices to progress through predefined display patterns

- RGB Neopixels can have multiple uses including that of rolled dice for poker, Yahtzee, etc.

- A jumper allows you to code for both RGB matrices independently (default) or combined into a single large matrix

- Utilizes a powerful Adafruit QT-PY SAMD21 or QT-PY RP2040 microcontroller

- Many SMT discrete components were used where possible

- On-board 500mA LiPoly battery charger

- Mounting holes are provided if you wish to use a 3D-printed case or project box

Software:

- Libraries and Neopixel learning document

- Optional Fast LED library

Software for 8x8x2 RGB Neopixel LED Board:

- Here are 52 RGB Neopixel LED display patterns I've written so far including:

   Beeps

   Blanks

   Dice

   Flash

   March/Fill

   Shapes

   Waves

- Games have yet to be designed
