Holybro BLHeli S 2-4S 20A ESC

S500 V2-BLHeli S 20A ESC

Main features
● EFM8BB21F16G MCU, pipelined 8-bit C8051 core with 50 MHz maximum operating frequency.
● Dedicated high frequency driver, makes the start more smooth. ESC maximum speed is 500k eRPM.
● BLHeli-S firmware is designed for superior performance in multirotors, and uses hardware generated motor
pwm for smooth throttle response and silent operation.
● Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active
freewheeling.
● Supports higher KV motor and more power load, more suitable for violent flight of racing drone .
● The code supports regular 1-2ms pulse width PWM input, as well as Oneshot and Multshot . The input signal is
automatically detected by the ESC upon power up.
● Supports Dshot150, Dshot300 and Dshot600.Dshot is digital signal, anti-interference ability is stronger, and
do not need throttle calibration.
● The silicone twisted-pair of the throttle signal cable increase the service life,and effectively reduces the crosstalk caused by signal transmission,and makes flight more stable.
