Precision I2C to PWM Converter for Standard ESC [ST]


This is a protocol converter designed to allow using standard ESC (Motor Controller) with I2C-based flight controllers such as MikroKopter. This converter uses ST chip for precise hardware PWM output.



  • I2C input from Mikrokopter or similar Flight Control supporting same I2C protocol
  • NEW I2C input from LotusRC T580 Flight Control (only supports 4 motors in this configuration)
  • output PWM signal suitable to standard motor controllers
  • supports 4 or 6 or 8 or 3 motor configuration
  • Configurable PWM frequency from 100 to 500Hz
  • Configurable emergency throttle in event of I2C disconnection
  • Configurable PWM pulse start / end points for custom ESC
  • Serial-console for configuration and firmware upgrade
  • Bind-plug feature to automatically calibrate all connected ESCs
  • Power by LiPo (up to 4S tested), 5V from 1st ESC (default), or external 5V from FC
  • RoHS-compliant
