# ESP32-S3 Arduino Uno
|
|
|
|
_ESP32-S3 Module embeded on Arduino Uno board_
|
|
|
|
|
|
|
|
## I2C Pins
|
|
|
|
The provided schematic excerpt below shows the wiring of SDA and SCL; SDA is wired to the GPIO 8 and SCL is wired to the GPIO 9 on the ESP32-S3 Module.

### 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")
|
|
#rint("MCU Temperature: ", esp32.mcu_temperature(), "C")
|
|
print("MCU Temperature: {:4.1f} C".format(esp32.mcu_temperature()))
|
|
|
|
# Configure LED pin and start the blinky loop thread
|
|
led = Pin(45, Pin.OUT)
|
|
led.value(0)
|
|
_thread.start_new_thread(status_led, ())
|
|
```
