✅ i also bought a "NodeMCU ESP8266 V3 12E". With this variant with the integrated ESP-12E (shielded)module, WIFI does not experience interference with pins D1 and D2!
This is how the modules differ visually:
"NodeMCU ESP8266 V3"
Says "Wemos". (link)
"NodeMCU ESP8266 V3 12E"
Says "Lolin" and has "ESP-12E" integrated. (link1)(link2)
thanks
