Plan not to loose more than 50mV from the source to the LED matrix. So that would be 50mV / 3.5A = 14 mΩ. For both supply wires, so 7mΩ each trace. A 1mm² copper cable has about 17.5mΩ/meter, so you'd ...

The PCB was developed to control any addressable RGB LED strip that uses WS2812B or similar LEDs that take 3 inputs (VCC, GND and Data/DIN) using any DIP8 packaged microcontroller. All board traces ...

Components Required to Build LED Tree Components required to build the RGB LED Tree are simple and can be found in your local hobby store Common Anode RGB LED - 10 470uF Capacitor - 3 82K Resistor - 3 ...

[Sayantan Pal] did this for the humble RGB LED matrix, creating an extra-thin version by recessing WS2812b NeoPixel LEDs inside a PCB. The popular WS2812B is 1.6 mm in height, which happens to be ...

[Stan] built this LED matrix using a 16×16 grid of RGB LEDs. He built the hardware and wrote some subroutines to randomize the colors. He’s not using PWM because frame buffering is not f… ...
