Documentation is Low, perhaps this helps

Documentation is Low .
would be finde if this would be linked.
https://github.com/Meshnology/meshnology_doc/tree/main/N40/N40_ESP32_Extension_Board

can someone acknoledge that the Yellow S pins are the 1:1 Pins of the Module. the green S Connectors are Level Shifted to 5V if external Power Source is attached.
If no external Power Source is attached ALL 5V connectors (red) are 0...

Nachtrag: Inzwischen habe ich herausgefunden: Die gelben mit S gekennzeichneten Dupont-Leisten sind 1:1 den jeweils grünen Schraubklemmen zuzuordnen. Die Frage des Jumpers, links unten, schaltet irgendwelche LEDs. Die Frage welche Bedeutung/ Funktion die Pins 13-14 im 8er -Block links, und P15-P16 im 8er-Block rechts haben erschließt sich mir noch nicht. Eventuell folgt ein weiteres Update.

Dokumentation

Das Board ist wirklich eine Bereicherung, und hat sehr viele Möglichkeiten, Anschlüsse des ESP32S3, nach Außen zuführen. Die Spannungsversorgung ist sehr gut gelöst, alles wie es besser nicht sein könnte. Aber es fehlt aneiner Dokumentation, der vielen Anschlüsse, wie die z.B. intern verdrahtet sind. Was ist mit dem Jumper, nur Deko? Dieser 3,3V Block, die 5V Dupontleiste, die S bezeichnet Leisten, wie sthen diese zu den Ausgängen des ESP usw.
