Q. Would this be one of the best choices to buffer the action of Raspberry Pi pin(s) when defined as output.
Is this 100% safe way of protecting the Pi even if the Pi pin is accidently redefined as an input pin when still wired as an output pin.
A. Hi N Chettleburgh. Thank you for your question. This should be fine to use when configured as an output. If left in the circuit and re-configured as an input, because of the high impedance we would think that it would do nothing and should not harm the Raspberry Pi.
