SimStack

SimStack Foundation Board

A SimStack consisting of a Foundation board, an Output board, and an Input board.

SimStack is a series of modular, stackable circuit boards enabling the integration of OEM and replica simulator parts with existing simulator software.

SimStack is available for sale in our Online Store.

SimStack Features

  • Connects real parts to your simulator software with little or no modification
  • Communicates via Ethernet, not USB, simplifying cabling, connectivity and compatibility
  • All logic is on each SimStack – no additional computer drivers are required
  • Professional circuit design, layout and manufacturing
  • Up to 128 digital inputs [1]
  • Up to 120 digital outputs [1]
  • Up to 16 analogue inputs [2]
  • Up to 4096 steps of Pulse Width Modulation on every digital output – for dimming LEDs or normal bulbs
  • Native in built H-Bridge for direct motor control
  • Supports output voltages between 0 and 32V DC
  • Supports high output current  – up to 3A per output and up to 30A per board
  • All outputs can be configured as common cathode or common anode (switched earth and switched supply)
  • Self-tightening spring connectors for connecting hardware – no soldering or terminations required
  • Based on Atmega hardware and software (C++) ensuring broad future compatibility
  • Configuration software is Java based and works across Mac, PC and Linux
  • For an example of the support hardare, please see the table below.
