Código main.py de exemplo:
#!/usr/bin/env pybricks-micropython

## exemplo
# fonte: https://docs.pybricks.com/en/v2.0/start_ev3.html
from pybricks.hubs import EV3Brick
from pybricks.ev3devices import Motor
from pybricks.parameters import Port

# Create your objects here

# Initialize the EV3 Brick.
ev3 = EV3Brick()

# Initialize a motor at port B.
#test_motor = Motor(Port.B)

# Write your program here

# Play a sound.
ev3.speaker.beep()

# Escrever na tela
ev3.screen.clear()
ev3.screen.print("Ola Mundo!")

# Falar
ev3.speaker.set_speech_options("pt-br")
ev3.speaker.say("Ola Mundo")

# Run the motor up to 500 degrees per second. To a target angle of 90 degrees.
#test_motor.run_target(500, 90)

# Play another beep sound.
ev3.speaker.beep(frequency=1000, duration=500)

Problemas encontrados sem uma explicação:

- Não use EFI em vez disso use:
bios: seabios

- Especifique o Display como Standard VGA (std), normalmente uso vga: serial0
vga: std
