A BLHeli S 20A ESC designed for use with Holybro’s 2207 KV1950 V2 Motor / QAV250 Quadcopter.
It comes pre-soldered with power wires and 2mm bullet connectors attacehd for a quick and easy installation.
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.
● 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 reduces the crosstalk caused by signal transmission and makes flight more stable.
