History of MicroPython

MicroPython was first created in 2013 by Damien George, a Ph.D. student at the University of Cambridge. It started as a Kickstarter campaign, which raised over $15,000.

The initial goal was to make Python accessible to microcontrollers, which are small computers that can be embedded into various devices. The idea was to make it easier for hobbyists and professionals alike to program microcontrollers, without the need for specialized knowledge, costly software or hardware, or extensive programming experience.

In 2014, MicroPython was released as an open-source project. It was designed to be a low-level system language, with a focus on efficiency, ease of use, and rapid prototyping.

It was initially targeted at ARM Cortex-M microcontrollers, but since then, it has been ported to a variety of microcontroller architectures, including the ESP8266 and ESP32.

Advantages of MicroPython over Other Programming Languages

Python is a popular programming language for a variety of applications, including web development, data analysis, machine learning, and more. MicroPython is a variant of Python, but it is optimized for microcontrollers.

Here are some of the advantages of MicroPython over other programming languages commonly used for microcontrollers.

Python-like Syntax

One of the biggest advantages of MicroPython is its Python-like syntax. Python is known for its simplicity, readability, and ease of use.

MicroPython uses the same syntax as Python, so anyone who knows Python can quickly learn MicroPython. This makes it easy for people without a programming background to get started with MicroPython.

MicroPython is designed to be efficient and fast, even on microcontroller platforms with limited resources. It is constructed on the C language, which is a low-level system language that offers good performance.

MicroPython programs are compiled to machine code, which results in faster execution times than interpreted languages like Python.

Small Footprint

MicroPython has a small footprint, meaning it takes up less space on the microcontroller than other programming languages. This is important because microcontrollers often have limited memory and storage, so using a language that takes up less space can be beneficial.

As MicroPython is a lightweight language, its compilation needs less storage space and execution speed is faster than interpreted languages.

Easy Debugging

Debugging in MicroPython is easy, as it supports serial communication that allows developers to use print statements for debugging. Developers using MicroPython can print out the variables and values to debug the program.

Serial communication makes it simple to connect to the computers terminal for debugging, which eliminates the need for expensive hardware or software.


MicroPython is a versatile language that can be used with different microcontrollers and peripherals. It supports a range of hardware, including sensors, displays, and communicators, and can interface with hardware using simple protocols like I2C and SPI.

This flexibility makes it a preferred choice for prototyping.

Electronics as a Hobby and a Career Path

MicroPython has gained a strong following within the electronics community over the years. Here are some of its benefits for hobbyists and professionals.

MicroPython Community and Contributions
