Features:
This hardware, with the SimonK firmware, gives you the perfect solution for multirotor use.
Highest efficiency 100% N-FET design.
No low voltage cutoff, because any cutoff in a multirotor = crash.
No over temp cutoff, because any cutoff in a multirotor = crash.
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.
