Put on your sunglasses before wiring up this LED matrix - 256
eye-blistering RGB LEDs adorn the NeoMatrix for a blast of
configurable color. Arranged in an 16x16 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 15 Amps per panel
if all LEDs are on bright white!) we suggest at least a 5V 10A power
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 2 or more panels
you may run low on RAM if you're using an UNO. Watch your power usage
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.
The LED are mounted on a flexible PCB - so you bend the panel to
perfectly fit your need!
