I've a question about level-shifting using mos. In my case I've several my devices that works at 3v3 and communicate between them using I2C bus. I must modify my board to communicate between them, but allowing to connect external boards (not from me) that use 5v as voltage level.
Schematic will result like this:
I'm sure I'll not have problem to interface 3v3 and 5v.
With two 3v3 I'll have something like this:
It should work with same principle. Can someone just check and (in case) confirm?
