Is there a list of which pins can be used for PWM on the XIAO-ESP32C3?

Also, what interrupts/counters are used for them?

Hi shmorgan,
“\Arduino15\packages\esp32\hardware\esp32\2.0.5\cores\esp32\esp32-hal-ledc.c and .h”
is useful to you?

[EDIT]
I checked and 6 channels of Ledc:0-5 are available. However, since there are only 3 Timers
Timer:0-2, 3 different frequencies can be set; 6 PWM can be assigned to any port of D0-D10 at the same time.

\Arduino15\packages\esp32\hardware\esp32\2.0.5\cores\esp32\esp32-hal-ledc.c : 35

Hi, so Check this Out . I was wondering that same thing, I looked at the Specifications comparison and it’s there about halfway down the page. 4 Analog pins too. Don’t want to ruin the fun or be a spoiler alert for you.
