Flexible Adafruit DotStar Matrix 8x32 - 256
RGB LED Pixels
PRODUCT ID: 2736
DESCRIPTION
-
For advanced DotStar fans, we how have a bendable, flexible 8x32 DotStar LED
Matrix! Control all 256 ultra-bright LEDs using only 2 microcontroller pins, set
each LED as you wish to scroll messages or draw little images. This matrix has a
thick flexible PCB backing that can be gently bent and curved around surfaces
These are the same integrated LEDs that are used in our new fancy DotStar strips.
This tiny 5050 (5mm x 5mm) SMD LED is the most compact way possible to
integrate multiple bright LEDs to a design. Rather than NeoPixels, this matrix uses
DotStar LEDs, which use a 2-wire protocol that is less timing-specific and has
high-frequency PWM for smoother color blending.
Don't forget, with 256 LEDs, you could use over 15A of current if you turn on all
the LEDs on to white (which we really do not recommend because we don't think
the flex PCB can handle that much current). Try to keep the current draw at under
5A, you can use our 5V 4A or 5V 10A power supply. For portable use, if you are
drawing less than 3A, try out this 5V@3A UBEC.
Like NeoPixels, DotStar LEDs are 5050-sized LEDs with an embedded
microcontroller inside the LED. You can set the color/brightness of each LED to 24bit color (8 bits each red green and blue). Each LED acts like a shift register,
reading incoming color data on the input pins, and then shifting the previous color
data out on the output pin. By sending a long string of data, you can control an
infinite number of LEDs. The PWM is built into each LED-chip so once you set the
color you can stop talking to the disk and it will continue to PWM all the LEDs for
you.

usage, etc!
Please note: Flexible PCBs are not designed for repeated flexing! While we think
this product may work in wearables 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 users only, who already know how to use NeoPixels
and are comfortable with the high current requirements and protecting the matrix
from damage. There are no returns, refunds or replacements for damaged product.
