Our High Voltage LED Driver is designed for powering a large LED matrix at voltages up to 35VDC.
The idea behind this is very simple. When making a large LED display with many LEDs (we're talking in the hundreds), you have two choices. You can wire the LEDs in parallel using a low voltage but at high current. Or you can wire the LEDs in series using a high voltage at low current. This design is based the latter with a high voltage and low current.
Note that a controller (not included) is required. For testing purposes we use the Arduino which works fine. There are various sites where you can get the code for programming the controller.
