ESP32 LILIGO 1.1 and LoRa boards with displays questions

Hello,

Does anyone know about those boards:
https://aliexpress.ru/item/4001237481336.html

https://aliexpress.ru/item/4000419738941.html

  1. Does their integrated-soldered OLED displays connected via SPI or I2C bus?
  2. Is it possible to use 2 independent I2C buses with this board - one for many slow modules with low rate, second clear for a 1 fast module to achieve max bus bandwidth?
  3. Where such boards store their WiFi-UI-firmware? If I will make my own programming and upload my sketch from ArduinoIDE - does WiFi-UI-firmware will be overwritten or will save?

4) Does LoRa blocks-replaces WiFi?
5) If I don't have any plans to peer ESP32 with each other, only connect them individually to the WiFi network - can such boards with LoRa bring any profit? Or they will be completely useless?

You have provided no context as to the intended use of the boards, but in general;

WiFi - High speed, very short distances, Worldwide frequency allocation, no duty cycle restrictions.

LoRa - Low speed, very long distances, Region specific frequency allocation, significant duty cycle restrictions.

It's an obvious. My questions is a little more precise and complicated.

Can anyone answer to questions 1-5?

A quick Google search for LILIGO ESP32 and the 3rd hit was for the LILIGO website with schematics etc.

I've already seen it.
There is no exact answers to my questions.
I can only assume the display is connected via SPI.
Question #2-5 are out from any scheme.

Why not buy one and find out?
They're dirt-cheap, and if it doesn't do exactly what you want, you could find inspiration to build something else.

Just in case you're unaware, most people here on the English forum don't speak or read Russian, so maybe here is a better place for your links.

If only you could think... you will understand that:

  1. Because to "find out" can waste 1 month of delivery.
  2. Try to find language switcher at right top, suppose you must know how your country flag looking?

If only you could think:

  1. you've got a lot of learning to do - that much is obvious - so a month is a useful timeframe.
  2. hey! now you've got a useful link that you can bookmark. And use.

I, and I suspect a lot of others, avoid clicking on Aliexpress links, specifically because to get my browser back to normal is a pain.

Do remember that the people you are asking for help are volunteers.

Dear friends,
All yours those claims have no real reasons. At those links you easily can switch language to any. Also it's possible to change language just by changing domain prefix from ".ru" to ".com". Both solutions are very easy and they do not deserve serious censure. Still OK, I will place links with En products description, its easy:
