[size=14.6667px]BLHeli_S is an improved version of the base BLHeli code.
[size=14.6667px]BLHeli_S delivers a throttle response that is [size=14.6667px]Smooth as Silk[size=14.6667px], and the main factor contributing to this, is that it uses hardware to generate motor PWM. Two MCUs support this for BLHeli_S, namely the BusyBee1 at 24MHz (EFM8BB10F8) and the BusyBee2 at 48MHz (EFM8BB21F16).
[size=14.6667px]BLHeli_S will have the same good [size=14.6667px]Sync[size=14.6667px] holding properties as base BLHeli. Maybe even better.
[size=14.6667px]BLHeli_S generally does [size=14.6667px]Startup[size=14.6667px] better than base BLHeli.
[size=14.6667px]BLHeli_S does damped light. Only.
[size=14.6667px]BLHeli_S has motor PWM that is [size=14.6667px]Synchronous[size=14.6667px] to the MCU master clock, as it is generated by hardware. This makes the motor [size=14.6667px]Silent[size=14.6667px].
[size=14.6667px]BLHeli_S has very [size=14.6667px]Small throttle Steps[size=14.6667px]. The resolution varies between hardware configurations (MCU clock speed and driver type), and is between a nominal 512 steps and 2048 steps.
[size=14.6667px]BLHeli_S supports very high motor [size=14.6667px]Speeds[size=14.6667px]. A BB1 MCU will support 350k erpm, and the limit of the BB2 is not yet known, so the code is set to limit at 500k erpm.
[size=14.6667px]BLHeli_S supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42 and Multishot. Autodetected when the ESC sees an input signal.
