There are 16 pwm channels on the rp2040 chip which can be connected to any
gpio. I'm sure that's still the same on the Tiny. So you have at least 8
pwm pins, or 11 if you count the rgb led. Not sure if the 4 adc pins can be
reconfigured to be digital pwm, but I don't think so.

(The Tiny has one more adc pin than the Pico because it lacks the
buck-boost and hence the need to monitor the input voltage. Like
(many/all/most?) small mcus, by the way, there is just one adc and the 4
pins are multiplexed.)
