Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : RP2040 is somewhat 5 Volt tolerant

And if you need to interface a LOT of GPIO between 3.3V and 5V, just buy some 74LVC245's.   https://cdn-shop.adafruit.com/datasheets/sn74lvc245a.pdf
