The SimStack Output Expansion Board delivers 16 high-current outputs per board. Up to seven of these boards can be stacked on top of a SimStack Foundation Board or other SimStack Expansion Boards, giving up to 120 outputs per stack. All output channels feature 4096 steps of Pulse Width Modulation — great for dimming both LEDs and incandescent bulbs, as well as powering a variety of other outputs. Each output can also be configured as switched supply or switched ground, providing increased flexibility and simplified wiring.
