I'm designing my first own PCB and I'm dealing with some RX and TX lines, which have to be shifted from 5V (controller) and 3V3 (GPS, XBee and so on). I want to make the level shifting as good as possible. I'm not sure which way to do it. At the moment I see two possibilities: First: http://faludi…
