Make mistakes, safely
No matter how skilled, we all make mistakes. In hardware projects, this means losing time and money. We designed SOLO with safety in mind. We offer protection against reverse polarity connections, output short-circuits, over-voltage, or under-voltage on your main supply input (BUS) and over-current consumptions. You now use motors with fewer worries.
For experts and non-experts alike
SOLO is easy but not simple. The experienced user will find many advanced functionalities. From sending packets through USB, UART, or CAN to use industrial state of the art technologies like Closed-loop and Open-loop, Sensored, Sensor-less, and Field-oriented control.
Simply control the speed, torque, and position of your motor’s shaft separately. Enjoy these features while SOLO automatically detects the motor’s parameters and self-tunes.
