NeoPixel 8x8 Matrix (64 LEDs)

Based on WS2812B RGB LEDs 

WS2812B based NeoPixel matrix modules contain 64 5050 RGB LEDs on 66mmx66mm (2.6-inch x 2.6-inch) PCBs.

Example Code:

We have a page dedicated to the setup, connection, and software necessary to drive a NeoPixel Ring set directly from an Arduino ATTiny85. 

Connection:

There are two sets of three connections on the 8x8 matrix.

• Input:
  • +5: Power (4v to 6v DC)
  • GND: Common Ground connection for signal and power
  • DIN: Input signal from your control processor

• Output:
  • +5: Power (4v to 6v DC)
  • GND: Common Ground connection for signal and power
  • DOUT: Output signal from your matrix board to connect to next module

Uses only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED.

The LED matrix is chain-able by connecting the output of one board into the input of another. There is a single data line. The drive protocol is very sensitive to timing. It requires a real-time microcontroller such as an AVR, Arduino, or PIC.
