I am trying to turn on or off a Raspberry Pi Pico using a Raspberry Pi Model 3.
The Raspberry Pi Pico seems to have a 3.3V_EN ping which is basically the 3.3V regulator enable pin (3V3_EN) pulled up to 5V through a 100K resistor internally.
I am confused how to use this pin using a 3.3V logic of the Raspberry Pi model 3 gpio pins to turn on or off the regulator inside the Pico.
From what I can see, the 5V will sink to ground if I pull the Raspberry Pi pin to ground but this pin is designed for 3.3V not 5V. It might damage the pin. On the other hand, what state should I keep the gpio pin so that it is basically floating and the Pico regulator is ON because of the internal pull-up. Kind of confused with this. Maybe I am missing something.
