DE-10 Nano GPIO's Query
Posted: Wed Mar 06, 2024 2:36 pm
Hi guys,
Dumb question here. I am working on a small project where I need to connect a 7-segments display. I was thinking to use 4 switches placed on a breadboard to select one of the 7 segments. Looking at the DE-10 Nano specifications, all the GPIO pins are 3.3V. Say for example that I want to connect each switch to the following pins:
GPIO_0[10]
GPIO_0[11]
GPIO_0[12]
GPIO_0[13]
Does that mean that I need to use a voltage divider to drop from 5v to 3.3v or can I safely connect 5V directly to the pins?
Many thanks in advance!
