Description
Note, while this speed control is universal and cool, we still have reasons for more simple implementations - those dissipate twice less power, are more comparct and cheap. If you don't need reverse and use brushed motors - consider alternate implementations, published here.
Features:
- For high voltage motors (100v, 220v) with power from AC.
- All motor types support.
- RPM stabilization, sensorless mode support (via back EMF).
- Hall sensor / Tacho generator can be used when available.
- Displays support:
- OLEDs with I2C bus
- Nextion with UART
- USB to configure from PC via serial terminal.
