But when MicroPython is claimed to be supported, it needs more than a vague link.
A fair comparison will be announcing support for Arduino but only provide a link to Arduino website.
I have a fair amount of boards with support for MicroPython or CircuitPython and I have at least a proper firmware for the board.
Drivers exists for LoRa and screen, I was successful in the past with a previous T-Watch.

Once more a company launch a product and do not provide proper documentation.
Maybe it's time to start shaming those companies as it is now a trend to push hardware to the market without anything on software side.

And they say to use micropython from here:

I found the schematic here:

There are never any MicroPython programming tips or example by LilyGO .
All the examples are C++, intended for the Arduino IDE !

Python may be fun and easy on established platforms like Adafruit boards, but...
There may be no drivers (called "libraries" in C language) for your LCD screen and LORA and you will have to program them yourself using low-level code.
C language is the most common language on Earth(!) Arduino boards were developed to use C (C++)15 years ago and there is a multitude of examples and libraries available, easily updated.

Simple Arduino IDE program:

//words preceded by "//"" are comments and are not executed
bool ticktock; //declare ticktock as a boolean flag

void setup() {          //runs once on start up
Serial.begin (115200); //open the serial port for USB cable
}

void loop() {         //runs in circles!
ticktock = !ticktock; //every pass through reverse the flag
  if (ticktock) {     //test current value of the ticktock flag
    Serial.println("tick");  
  } else {             //prints one or the other to the USB port
    Serial.println("tock");
  }
delay (1000);           //wait for a second and run again!
}

This program will compile and run on literally thousands of microcontrollers!
