Wiring is simple: there are two 3-pad connection ports on the back. Solder the wire to the input port (+5V GND DIN) and provide 5VDC for the +5V and ground pins, then connect the DIN pins to the microcontroller. You also need to establish a common ground from the 5V power supply to the microcontroller /XArduino. Since each LED can consume up to 40mA of current (up to 2.5 amps per panel if all are bright white!)
Don’t eat this LED grid just because it’s so colorful and bite-sized! This is the smallest small LED grid make, with 1 full RGB color pixel in a square that is only 64 inchx 1 inch square (for metric enthusiasts, this is 24.4+ -mm x 24.4+ -mm). Best of all, these are small DotStar with built-in PWM drivers, so you only need two digital I/O pins to get the glow.
But don’t be fooled by their small size, each LED is still and dazzling in brightness, just like the DotStars/NeoPixels you know and love. These integrated are the same ones used in our new fancy DotStar light strips, just very small. Arranged in an 8×8 , each pixel is individually addressable: like , DotStar have an embedded microcontroller inside the LED. You can set the color/brightness of each LED to a 24-bit color (8 bits each for red, green, and blue).
Each LED acts like a shift register, reading the input color data on the input pin and then moving out the previous color data on the output pin. By sending a long string of data, you can control an inchunlimited inch number of . PWM is built into each LED chip, so once you set the color, you can stop communicating with the disk and it will continue PWM all the .
If you plan to use full brightness and a lot of white, we recommend you use a 5V 2A power supply. for most uses, you’ll see about 0.5A of current per panel, and you can set the brightness to lower that current. Note that the current passing through the plate is so large that it becomes hot! These are packaged very tightly on a small PCB, do not adjust them all to bright white, or you may overheat and melt the board.
