Alright. I’ve seen that. I’ve cited it.
What I was asking was whether I can assume based on that label
+3V3 for pin 1 that I can connect to RxD (pin 2) and TxD (pin 3) with 3.3 V (or whether there is a convention that basically implies this). And I explicitly stated that I don’t want to connect to pin 1 at all (because that’s not needed for my use case). So what I was “doubting”, as you put it, was not whether the
+3V3 label for pin 1 was correct (I can measure that), but whether that holds true for the other two pins as well. After all digital signals won’t show up as a discrete voltage level on a voltmeter and I am not equipped with an oscilloscope. So better safe than sorry …
This may be perfectly logical for you if you are aware of such a convention, to me it wasn’t and in fact I still don’t know if this is a convention (which I could apply in the future) or whether it was an assumption that you tried without frying your hardware, for example.
Thanks a bunch for the answer in any case
