The pin map & schematic is pretty much exactly like you get with Adafruit or Sparkfun and so forth, so what are you hoping for here? The documentation is not “wildly unreasonable, illogical, or inappropriate” however Heltec’s docs do tend towards “arousing amusement or derision” due to some inaccuracies.
If I have a question not readily answered by the pin-map that shows the ones broken out on the board plus the schematic to cross reference, the very first person I’d ask would be @BNS as he knows this module really well, @Ashley is staff and @dstacer’s answer is pretty much in line with where I’d start.
As I’m 2.375 times older than @BNS you are going to have to find a new insult for the kiddo bit. But I’d strongly suggest not bothering with any form of insults because not only will it not get you any answers, it won’t inspire anyone to answer any real questions you may have in the future.
