SimStack Stepper is an Ethernet-controlled stepper motor with angular position accuracy of 0.1 degrees. It builds on the Tropical Labs Mechaduino, adding Ethernet connectivity that integrates directly with SimStack Switch.
The SimStack Stepper is coupled to a NEMA 17 stepper motor with a built-in Hall-effect sensor, providing accurate closed-loop position data.
Our solution supports both directly coupled and geared installations. Thanks to the closed-loop design the motor never loses steps, bringing a new level of accuracy to analogue instruments. In a directly coupled configuration no external position sensing is required; geared installations need an external position sensor such as a 10-turn potentiometer, a physical switch, or an optical sensor.
Customised firmware is provided to suit each installation where SimStack Stepper is used, such as:
- Artificial horizon – roll control
- Analogue altimeter
- Pressurisation gauge
- Whiskey compass
- Airspeed indicator
