20x20mm installation design, further reducing the size and weight. Support 24K-128KHz PWM refresh rate, The built-in fuel gauge allows the flight controller to monitor the current and voltage in real time. The installation hole is equipped with a shock-absorbing mechanism, which effectively reduces the impact of external vibration on the high-sensitivity components of the ESC. And provide first-level shock absorption protection for the upper flight control and other equipment. Support the latest DS ultra-high speed digital throttle. Strong anti-interference ability, Quick response. It also supports common PWM, Ones and Multis and Pros and other throttle signals. The third-generation BLHeli-32 firmware has powerful performance and rich functions; and supports multiple ways to set ESC parameters, or upgrade ESC firmware (such as through the throttle) signal line, use other development boards, Or use the cleanflight or betaflight firmware flight controller to set up or upgrade the ESC.
