64x32 Flexible RGB LED Matrix - 4mm
Pitch
PRODUCT ID: 3826
If you've played with multiplexed RGB matrices, you may have wondered "hey,
could we possibly manufacture these on a thin enough PCB, so it's flexible?" and
the answer is Yes! This LED panel is just like rigid 64x32 style ones, but without
the plastic supports. This matrix has a thin, bendable PCB backing that can
be gently bent and curved around surfaces.
Please note: Flexible PCBs are not designed for repeated flexing! While we think
this product may work in wearables or architectural lighting, or other situations
where the matrix is bent around, we do not offer any guarantees or refunds if
you end up cracking the LEDs or traces! This is for advanced makers only, who
are comfortable with the high current requirements and protecting the matrix
from damage. There are no returns, refunds or replacements for damaged
product.
This version is the 4mm pitch 64x32 Flexible RGB LED Matrix. Please note you
cannot use an Arduino UNO to drive this size. It's way too big! Use an Arduino
Mega, Raspberry Pi, BBB or other device that can handle displaying to RGB
matrices and has plenty of RAM.
This matrix has 2048 bright RGB LEDs arranged in a 64x32 grid on the front. On
the back there are two IDC connectors (one input, one output: in theory you can
chain these together) and 12 16-bit latches that allow you to drive the display
with a 1:16 scan rate.
These displays are technically 'chainable' - connect one output to the next input
- but our Arduino example code does not support this (yet). You're best off
using a Raspberry Pi or other fast computer that can drive RGB matrices.
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:
A single 64x32 RGB panel
An IDC cable
A plug in power cable
6 mounting screws
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.
Please note:
The back color of the matrix may vary
There may be reworked pixels with flux. We do not guarantee perfectly
pristine panels
This product may come with one or two power connections
