### Micropython LED Blinky Code
``` python
import esp, esp32, time, os, _thread
from machine import Pin, SoftI2C
# An infinite loop thread to blink LED
def status_led():
# Blink pattern blink-blink-pause
while True:
led.value(1)
time.sleep_ms(250)
led.value(0)
time.sleep_ms(250)
led.value(1)
time.sleep_ms(250)
led.value(0)
time.sleep_ms(750)
# Display information about ESP32S3 module
print(os.uname())
print("Flash size: ", esp.flash_size()/1024/1024, "Mb")
