ADAFRUIT NEOPIXEL NEOMATRIX 8X8 - 64 RGB LED PIXEL MATRIX
DESCRIPTION
Put on your sunglasses before wiring up this LED matrix - 64
eye-blistering RGB LEDs adorn the NeoMatrix for a blast of configurable color.
Arranged in an 8x8 matrix, each pixel is individually addressable. Only one
microcontroller pin is required to control all the LEDs, and you get 24 bit
color for each LED.
Wiring it up is easy: there are two 3-pin connection ports.
Solder wires to the input port and provide 5VDC to the +5V and ground pins,
then connect the DIN pin to your Microcontroller. If you're using our NeoPixel
Arduino library, use digital #6. You'll also need to make a common ground from
the 5V power supply to the
microcontroller/Arduino. Since each LED can draw as much as 60mA (thats up to
3.5 Amps per panel if all LEDs are on bright white!) we suggest our 5V 2A power
supply. For most uses, you'll see about 1-2A of current per panel.
If, say, you need MORE blinky, you can chain these together.
For the second shield, connect the DIN connection to the first panel's DOUT.
Also connect a ground pin together and power with 5V. There you go! You can
chain as many as you'd like although after 4 or more panels you may run low on
RAM if you're using an UNO. Watch your power usage too, you may need a 5V 10A
power supply for so many of these!
There is a single data line with a very timing-specific
protocol. Since the protocol is very sensitive to timing, it requires a
real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be
used with a Linux-based microcomputer or interpreted microcontroller such as
the netduino or Basic Stamp. Our wonderfully-written Neopixel library for
Arduino supports these pixels! As it requires hand-tuned assembly it is only
for AVR cores but others may have ported this chip driver code so please google
around. An 8MHz or faster processor is required.
