What is the PWM frequency of the attny13a based driver?

I want to know the PWM frequency of this driver:
RMM driver link

Does the firmware affect what frequency it will have?
I have the guppydrv firmware on it.

Thank you. (;


The PWM frequency is set by firmware. Stock frequency of the qlite firmware is ~18kHz. A different firmware can apply a different frequency.

Thank you very much (:
