Same class, but the hardware has a different limit -- like Jan said, it goes up to 40kHz on ESP32.

The docs you're looking (that mention the 1kHz limit) are for the ESP8266 specifically.
Why have the timers been limited so slow??

I had to create a clocking signal fro another component and using Lobo ESP32 firmware I was creating square waves in the MHz using it's timers. see https://github.com/loboris/MicroPython_ ... o/wiki/pwm
