MR-20A PRO ESC is a high speed and high efficiency controller with MCU (F396) working under 48Mhz, 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 PRO, 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 PRO 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.
