What makes SEFM different?

  • Totally new MCU that comes with a three channel PMW output specifically designed for motor control applications and runs at 48mhz.

  • Higher quality MOSFETs with extremely low internal resistance
  • Three exceptionally fast dedicated MOSFET drivers
  • Extra capacitance to help remove EMF spikes and keep the rest of your equipment safe.
