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.
