MR-20A Brushless speed controller

MR-20A ESC is a high speed and high efficiency controller specially designed for multirotor quadcopter. Its high speed means not only the high fidelity driving signal from high side N-MOS fets (Because of the G pole capacitor influence of N-MOS, the high side N-MOS fets driving signal on normal ESC will be deformed and its efficiency will be low too), but also means a completed and high fidelity high voltage driving signal of low side N-MOS fets ( The low side N-MOS for normal ESC is driven by 5V, but for our MR-20A, the driving voltage for low side N-MOS is same as the power, so the efficiency would be higher than normal ESC)
       In total, the not deformed driving signal of both high side and low side N-MOS, with the same driving voltage, the perfect consistency of both low side and high side N-MOS makes MR-20A ESC much better for aggressive 3D FPV flying than any other ESCs.
    Besides, we designed the connection port a half round metal hole, so the ESC can be integrated on your multirotor without cable connection.
