The ESC is slim so can fit within 16MM booms.\u003c\/p\u003e\n\u003cp\u003eIt comes with long wires and pre-soldered connectors for a quick and easy installation – please select connector option as required.\u003c\/p\u003e\n\u003cp\u003eMain features\u003c\/p\u003e\n\u003cp\u003e● 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.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCon.
