000 – ESP32 MicroPython: How to Get Started with MicroPython
In this article you will learn how to get started with MicroPython explorations. We will begin to learn to install first a Thonny Python IDE for developing MicroPython codes for development board of your choice. I will be using an ESP32 development board.
Instructions:
1. Download the Thonny Python IDE at:
Download Thonny Python
This is one of the best, beautiful, and beginner-friendly IDE available. We will also use Thonny Python to erase and flash new firmware to ESP32 with the help of esptool pluggins.
2. Download the MicroPython firmware from:
Download Firmware at MicroPython.org
Go to download section and look for your development board. Choose the stable bin file for your board.
3. Download the ESP32 USB driver at:
Download ESP32 USB driver
4. Download some references files for your development board like pinouts and schematic diagram.
5. Install Thonny Python
6. Install the ESP32 USB driver
7. Flash a new firmware to ESP32 using the Thonny Python.

Example 1, Turn ON or turn OFF the onboard LED
# Load the 'machine' module to access the hardware
import machine
# Create an 'led' object in pin 2
# and set the pin direction to output
led = machine.Pin(2, machine.Pin.OUT)
# This turns on or turns off the 'led'
led.on()
led.off()
# This is the same as the above code
# but now we are passing a value
led.value(1)
led.value(0)
# This is the same as the above code
# as you already know
# 1 = True
# 0 = False
led.value(True)
led.value(False)
Example 2, Blink the onboard LED
# Load the 'machine' module to access the hardware
import machine
# Load the 'time' module which includes the 'sleep' class
import time
# Create an 'led' object in pin 2
# and set the pin direction to output
led = machine.Pin(2, machine.Pin.OUT)
# Create an eternal loop that blinks the LED
# time.sleep(0.5) creates a 0.5 second delay
# or 500 milli seconds
while True:
led.on()
time.sleep(0.5)
led.off()
time.sleep(0.5)
CP210x Universal Windows Driver fails every time. How can I solve it? Thank you
@Nicat, under the Software Downloads > Downloads:
Try to use CP210x Universal Windows Driver
v10.1.10
nice tutorial, I able to run my first mycropython code in esp32. Thank's a lot george
@Bayu Permadi, I am glad that it helps you get started with MicroPython. Thank you and congratulations in your progress. Cheers.
Thank You very mutch for all
hello , help please, I have esp32-s3 and priogramming with Thonny .
Programming is OK , but in shell I have continuos " invalid header:0xfffffff
Hi Paolo, I don’t have ESP32-S3 at hand to test. Anyways, did you download the correct firmware from https://micropython.org/download/ ? In your case, it should be the ESP32-S3.
Please let me know if you solve this case.
Cheers.
Hi Guys
I did every thing as explained but when I lunched Thonny and tried to install esptools
I got the message

Device is busy or does not respond. Your options:
– wait until it completes current work;
– use Ctrl+C to interrupt current work;
– reset the device and try again;
– check connection properties;
– make sure the device has suitable MicroPython / CircuitPython / firmware;
– make sure the device is not in bootloader mode.
