These displays are technically 'chainable' - connect one output to the next input - but our Arduino example
code does not support this (yet).
These panels require 13 digital pins (6 bit data, 7 bit control) and a good 5V supply, up to 4A per panel. We
suggest our 4A regulated 5V adapter and then connecting a 2.1mm jack. Please check out our tutorial for
more details!
Comes with:
o A single 64x32 RGB panel
o An IDC cable
o A plug in power cable
o We also include 4 mounting screws and mini-magnets (it appears these are often mounted on a
magnetic base)
Keep in mind that these displays are designed to be driven by FPGAs or other high speed processors: they
do not have built in PWM control of any kind. Instead, you're supposed to redraw the screen over and over
to 'manually' PWM the whole thing. On a 16 MHz Arduino Mega, we managed to squeeze 12-bit color
(4096 colors) with 40% CPU usage but this display would really shine if driven by any FPGA, CPLD,
Propeller, XMOS or other high speed multi-core controller. The good news is that the display is pre-white
balanced with nice uniformity so if you turn on all the LEDs it's not a particularly tinted white.
Of course, we wouldn't leave you with a datasheet and a "good luck!" We have a full wiring diagrams and
working Arduino library code with examples from drawing pixels, lines, rectangles, circles and text. You'll
get your color blasting within the hour! On an Arduino, you'll need 16 digital pins, and about 3200 bytes of
RAM to buffer the 12-bit color image. https://cdn-learn.adafruit.com/downloads/pdf/32x16-32x32-rgb-led-
