I need to make a UART connection between these two board but since the Nano works at 5 V and the raspberry works at 3.3 V I need additional components.
My question is: is it enough to use a simple voltage divider with a couple of resistors and how reliable and safe is it?
I want to use the resistors because I don't have time to order new components and wait for them to arrive.
Thanks in advance
