Hardware overview

Originally designed to switch high power LEDs, a high power switch array can prove to be useful in a variety of applications. A circuit design is based on TC4427 driver and n-channel MOSFETs (irfz44n or any other MOSFET which gate’s threshold voltage is 5V or higher). The high power switch array works with 12V5A line, which can be accessed from the main hub or the 12V5A breakout

Programming switches

A high power switch array is a simple logic buffer meaning that if a respective pin is HIGH, a corresponding pin of the switch is HIGH too.

Safety

Do not connect or disconnect connectors while power is ON. All adjustments must be done ONLY when power is OFF.
