• BLHeli_S delivers a throttle response that is smoother than previous BLHeli, thanks to the hardware PWM. 
  • It will have the same good sync holding properties as base BLHeli.
  • BLHeli_S does damped light only.
  • It has motor PWM that is Synchronous to the MCU master clock, as it is generated by hardware. This makes the motor run more silently.
  • It has very small throttle steps. The resolution varies between hardware configurations (MCU clock speed and driver type), and is between a nominal 512 steps and 2048 steps.
  • Supports very high motor Speed: BB2 is set to 500k eRPM.
  • Supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42 and Multishot. Auto-detected when the ESC sees an input signal.
  • Firmware upgradable via the signal wire - cleanflight passthrough
