NEW PRODUCTS – Flexible Adafruit DotStar Matrix 8×8 – 64 RGB LED Pixels / Flexible Adafruit DotStar Matrix 16×16 – 256 RGB LED Pixels / Flexible Adafruit DotStar Matrix 8×32 – 256 RGB LED Pixels
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, DotStar LEDs use a 2-wire protocol that is less timing-specific and has high-frequency PWM for smoother color blending.
Like NeoPixels, DotStar LEDs have an embedded microcontroller inside the LED. You can set the color/brightness of each LED to 24-bit 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.
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 DotStar LEDs and are comfortable with the high current requirements and protecting the matrix from damage. There are no returns, refunds or replacements for damaged product.
Put on your sunglasses before wiring up this LED matrix – 64 eye-blistering RGB LEDs adorn the Adafruit DotStar Matrix for a blast of configurable color. Arranged in an 8×8 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.
With 64 LEDs, you can have up to 4A of current draw if all the LEDs are on bright white. You can use our 5V 4A, 5V 2A or even a 5V 10A power supply. For portable use, if you are drawing less than 3A, try out this [email protected] UBEC.
For advanced DotStar LED fans, we now have a bendable, Flexible 16×16 Dotstar LED Matrix! Control all 256 ultra-bright LEDs using only two 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
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 [email protected] UBEC.
For advanced DotStar fans, we how have a bendable, flexible 8×32 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.
