Main Features:
This hardware， with the SimonK firmware， gives you the perfect solution for multirotor use
N-FET design
High accuracy with crystal oscillator ( temperature won't affect the PWM operating range )
No low-voltage cutoff
No over-temperature cutoff
Super high refresh rate， no buffering of the input signal， resulting in more than 490Hz response rate
16KHz motor frequency， giving fastest response of the motor， and quietest operation as well ( no 8KHz squeal )
Super simple， foolproof operation! Nothing to program other than the throttle range
