The maximum output frequency | Microcontroller › Arduino › Max. frequency output from arduino › The maximum output frequency March 21, 2016 at 12:57 pm #13804 Prabakaran P MParticipant The maximum output frequency is based on the clock we are using with Arduino. As u told 65KHz is the maximum for Arduino UNO, pro mini etc. The only way i found is to go for higher end Arduino for higher frequencies.
