How to install micropython on esp8266 node mcu

micropython is a lean and efficient implementation of python 3 for microcontrollers and embedded systems. installing micropython on an esp8266 nodemcu is a great way to leverage the power of python in your iot projects. below is a step-by-step tutorial on how to install micropython on an esp8266 nodemcu.

### step 1: download the micropython firmware
2. select the appropriate firmware for the esp8266 nodemcu. you can choose between the stable version or the latest release.
3. download the firmware file (usually in .bin format) to your computer.

### step 2: install esptool
1. install esptool, a tool for flashing firmware onto esp8266 boards.
2. you can install esptool using pip by running the following command in your terminal:



### step 3: erase the nodemcu flash memory
1. connect your esp8266 nodemcu to your computer using a usb cable.
2. find out the port that the nodemcu is connected to (e.g., com3 on windows or /dev/ttyusb0 on linux).
3. run the following command to erase the flash memory of the nodemcu (replace `/dev/ttyusb0` with your actual port):



### step 4: flash the micropython firmware



### step 5: accessing the micropython repl
1. once the firmware is successfully flashed, disconnect and reconnect the nodemcu to your computer.
2. use a serial terminal program like putty (windows) or minicom (linux) to connect to the nodemcu's serial port at a baud rate of 115200.
3. you should see the micropython prompt (``) indicating that you have successfully installed micropython on your esp8266 nodemcu.
