I'm working on a project using a Raspberry Pi 4 to send control pulses to an external circuit. The GPIO ports on the Pi are at 3.3V high. The external circuit expects high signals of 12V. I came across a thread on this forum of someone who also needed to level shift 3.3V logic to 12V: …

Level shifting 3.3V to 12V without inversion

@LarryD couldn't this be achieved with a single MOSFET without the need for inverting?
