Shift Driver 48-Channel [kit]

This is a board we were working on for a personal project, and thought others might be able to put it to use as well.

Using just a few i/o pins from your micro-controller the Shift Driver board will allow you to control up to 48 output channels. The outputs feature high voltage and high current capabilities. (50V / 500ma/channel)

Two separate common output rails can be ganged together for, or used separate to allow for driving a combination of output devices with up to two different voltages. (For example 24 24v solenoids on one rail and 24 12v relays on the other 24 outputs.)

Perfect for driving relays, hammer/solenoids, lamps, high power led's etc. Incorporate into your organ, glockenspiel, xylophone or other automation project.
