Best Alternatives to CircuitPython

CircuitPython has become a popular programming language and platform for creating interactive hardware projects, especially in the realm of microcontrollers and single-board computers. It’s known for its ease of use, simplicity, and focus on education and accessibility. However, there are several alternatives to CircuitPython, each with its own strengths and suitability for different projects. In this essay, we’ll explore some of the best alternatives to CircuitPython and delve into their features, ecosystems, and use cases.


MicroPython is one of the closest alternatives to CircuitPython, as both are derived from Python and tailored for microcontroller development. MicroPython offers a similar syntax and programming experience, making it easy for users familiar with CircuitPython to transition. It supports a wide range of microcontroller platforms and single-board computers, including popular ones like ESP32, ESP8266, and Raspberry Pi Pico. MicroPython has a vibrant community and extensive documentation, making it a strong choice for projects requiring low-level hardware control and embedded development.

Arduino IDE:

Arduino IDE is a popular development environment for programming Arduino boards, which are widely used in electronics projects and prototyping. While Arduino IDE uses a different programming language (a simplified version of C++), it offers a beginner-friendly environment with a simple and intuitive interface. Arduino boards support a vast ecosystem of sensors, actuators, and shields, making them suitable for a wide range of projects, from simple blinking LED experiments to more complex robotics and IoT applications. Arduino IDE’s extensive libraries and community support make it a compelling alternative to CircuitPython, especially for users interested in physical computing and electronics.


PlatformIO is an open-source ecosystem for IoT development that supports multiple hardware platforms, including Arduino, ESP8266, ESP32, and many others. Unlike CircuitPython, which focuses on simplicity and ease of use, PlatformIO offers advanced features such as multi-platform support, project management, and integrated development environments (IDEs) like Visual Studio Code. PlatformIO provides a unified development experience across different microcontroller architectures and offers features like code completion, linting, and debugging, making it suitable for more complex and professional-grade projects.

Raspberry Pi OS (formerly Raspbian):

Raspberry Pi OS is the official operating system for Raspberry Pi single-board computers. While it doesn’t directly compete with CircuitPython in terms of microcontroller development, Raspberry Pi OS offers a powerful platform for programming and prototyping with Python. Users can leverage the Raspberry Pi’s processing power, memory, and connectivity options to create a wide range of projects, from home automation systems to multimedia centers. Raspberry Pi OS provides access to Python libraries and development tools, making it a versatile alternative for users interested in exploring Python-based projects beyond microcontrollers.


NodeMCU is an open-source firmware and development kit for ESP8266-based microcontroller boards. It uses the Lua scripting language, offering a different programming paradigm compared to CircuitPython’s Python-based approach. NodeMCU provides built-in support for Wi-Fi connectivity and features like GPIO, SPI, and I2C, making it suitable for IoT and wireless networking projects. While NodeMCU’s Lua-based programming may require users to learn a new language, it offers a lightweight and efficient runtime environment for embedded development.


Espruino is an open-source JavaScript interpreter for microcontrollers, providing a high-level scripting environment similar to CircuitPython. It supports a variety of hardware platforms, including boards based on STM32, ESP32, and Nordic Semiconductor chips. Espruino offers features like on-the-fly compilation, interactive REPL (Read-Eval-Print Loop), and extensive built-in libraries for interacting with hardware peripherals. While Espruino’s JavaScript-based approach may appeal to users comfortable with web development, it offers a seamless experience for prototyping and deploying embedded projects.

Mongoose OS:

Mongoose OS is an open-source operating system for IoT devices that supports microcontroller platforms like ESP32 and ESP8266. It offers over-the-air (OTA) updates, remote device management, and cloud integration, making it suitable for scalable and connected IoT applications. Mongoose OS supports C/C++ and JavaScript programming languages, allowing users to choose the language that best suits their project requirements and expertise. With its focus on connectivity and cloud integration, Mongoose OS provides an alternative to CircuitPython for building IoT solutions.

Final Conclusion on Best Alternatives to CircuitPython

In conclusion, while CircuitPython excels in simplicity and ease of use for microcontroller development, several alternatives offer different features, ecosystems, and programming paradigms.

Whether it’s MicroPython for a similar Python-based experience, Arduino IDE for a beginner-friendly environment, PlatformIO for professional-grade development, Raspberry Pi OS for exploring Python-based projects on single-board computers, NodeMCU for Lua-based IoT development, Espruino for JavaScript scripting, or Mongoose OS for scalable IoT solutions, developers have a range of options to choose from based on their project requirements, expertise, and preferences.

Ultimately, the best alternative to CircuitPython will depend on the desired features, hardware compatibility, ecosystem support, and project complexity.
