## Article

## **SimStack Stepper**

SimStack Stepper features an Ethernet controlled Stepper Motor with angular position accuracy of 0.1 degrees. This product builds on the [Tropical Labs Mechaduino](https://tropical-labs.com/mechaduino/)by introducing an Ethernet connectivity that integrates directly with [SimStack Switch](https://simulatorsolutions.com.au/simulator-solutions-software/simstack-switch/).

The SimStack Stepper is coupled to a NEMA 17 stepper motor with a built-in Hall Effect sensor to provide accurate position data in a closed loop format.

Our solution can support both directly coupled and geared installations and owing to the close loop design, the motor will never lose steps. This introduces a new level of accuracy for analog instruments.

When used in a directly coupled configuration, no external position sensing hardware is required. Geared installations will require an external position sensor which can be a 10 turn potentiometer, a physical switch or optical sensor.

Customised firmware is provided to suit each installation where SimStack stepper is used, such as;

- Artificial horizon – roll control

- Analog altimeter

- Pressurisation Gauge

- Whiskey Compass

- Airspeed indicator
