Numeric Through-Hole, Clock High Temp LED Displays QuasarBrite LED Displays LED Displays are an ideal technology for markets such as industrial controls, medical devices, set-top box communications equipment, white goods and aerospace. I have a 1uF capacitor between the power and ground. I'm using a 10k resistor between pin 16 and the power on the max7219. It is ideal for use in applications requiring high quality. I have read that the max7219 cannot drive some higher-power White LEDs because of voltage requirement, but since all of the White Matrix seems to power up, I'm not sure that is the problem. The FND-5881W4SM00BW35 from Forge is a column cathode (60mm) 8 x 8 white dot matrix display. When I start to send data to the max7219, the next Green array driven by the second max7219 displays the appropriate image, but in the White Matrix all of the LEDs remain on, but their brightness seems to dim slightly with the data changes. Here's what happens when I swap out the Green Matrix for the White Matrix on my breadboard: All of the LEDs on the White Matrix power on immediately when the power to the Arduino is turned on. I figured (not knowing too much about electronics) that since the pin configuration of the matrix was the same, this wouldn't require too much require too much fiddling to get the White Matrix to work. For the project that I'm working on, I decided to switch from a Green LED matrix: 1.Underpinning the LED Matrix is the soldering of each LED in the matrix into columns of Anodes and rows of Red, Green and Blue Cathodes (for Common Anode LED.
