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 independent digital inputs [1]
- Up to 120 independent digital outputs [1]
- Up to 16 analogue inputs
- 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 (fused)
- 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
- For an example of the support hardware, please see the table below.
