and it works fine for me (on 3,3V and then I tried 5V as well).

I will try to order another 2x4 module and I am curious if it will work.

There are many manuals and videos with ESP8266 and MAX7219 that describe 3V power - e.g. https://mytectutor.com/how-to-control-max7219-led-matrix-with-esp8266-nodemcu-over-wifi/?utm_content=cmp-true I tried 5V for sure (without level shifter - to be honest I have no idea what should I use).

Signal strength around -60 to -70 dBm - I would say probability of working connection increased with stronger signal level. Then I tr...

I bought a few devices last week - NodeMCU v3 (ESP8266), ESP32 30pin and ESP32 38pin. I flashed latest ESP Easy build mega-20221105 - then I connected to AP and set my WiFi and was awaiting it will connect my WiFi successfully - the same way I have other ESP8266 devices already connected on my WiFi....
