Small Satellite Solar Array Drive Electronics (SADE)
The small satellite Solar Array Drive Electronics (SADE) controller is compact solution for interfacing with our small satellite Solar Array Drive Assembly (SADA). The SADE consists of a serial RS-422 interface to receive commands and send telemetry to the spacecraft host. The SADE is a motor driver capable of controlling current and speed of the motor via commands provided by the spacecraft host. The SADE is comprised of space rated radiation tolerant components capable of operating in a LEO environment.
Key Features:
- LEO orbit capable/radiation tolerant
- RS-422 serial interface for spacecraft communications
- Stepper motor current and speed control
- Onboard temperature sensor
- Compact driver design
