`!CircuitPython`!`:cite-ref-5[`F5bf`_`[5`#cite-note-5]`_`f] is an open-source derivative of the `F33f`_`[MicroPython`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=MicroPython]`_`f programming language targeted toward students and beginners. Development of CircuitPython is supported by `F33f`_`[Adafruit Industries`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Adafruit_Industries]`_`f. It is a `F33f`_`[software`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Software]`_`f implementation of the `F33f`_`[Python`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Python_(programming_language)]`_`f 3 `F33f`_`[programming language`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Programming_language]`_`f, written in `F33f`_`[C`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=C_(programming_language)]`_`f.`:cite-ref-cp-github-3-1[`F5bf`_`[3`#cite-note-cp-github-3]`_`f] It has been ported to run on several modern `F33f`_`[microcontrollers`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Microcontroller]`_`f.

CircuitPython consists of a Python compiler to bytecode and a runtime interpreter of that bytecode that runs on the microcontroller hardware. The user is presented with an interactive prompt (the `F33f`_`[REPL`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Read–eval–print_loop]`_`f) to execute supported commands immediately. Included are a selection of core Python libraries. CircuitPython includes modules which give the programmer access to the low-level hardware of supported products as well as higher-level libraries for beginners.`:cite-ref-6[`F5bf`_`[6`#cite-note-6]`_`f]

CircuitPython is a fork of MicroPython, originally created by Damien George.`:cite-ref-7[`F5bf`_`[7`#cite-note-7]`_`f] The MicroPython community continues to discuss`:cite-ref-8[`F5bf`_`[8`#cite-note-8]`_`f] forks of MicroPython into variants such as CircuitPython.

CircuitPython is targeted to be compatible with `F33f`_`[CPython`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=CPython]`_`f, the reference implementation of the Python programming language.`:cite-ref-9[`F5bf`_`[9`#cite-note-9]`_`f] Programs written for CircuitPython-compatible boards may not run unmodified on other platforms such as the `F33f`_`[Raspberry Pi`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Raspberry_Pi]`_`f.`:cite-ref-10[`F5bf`_`[10`#cite-note-10]`_`f]

>>Usage

CircuitPython is being used as an emerging alternative solution for microcontroller programming, which is usually done in C, C++, or assembly. The language has also seen uptake in making small, `F33f`_`[handheld video game`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Handheld_video_game]`_`f devices.`:cite-ref-11[`F5bf`_`[11`#cite-note-11]`_`f] Developer Chris Young has ported his `F33f`_`[infrared`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Infrared]`_`f transmit-and-receive software to CircuitPython to provide interactivity and to aid those with `F33f`_`[accessibility`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Accessibility]`_`f issues.`:cite-ref-12[`F5bf`_`[12`#cite-note-12]`_`f]

>>>Blinka Software Abstraction Layer

CircuitPython code may run on `F33f`_`[MicroPython`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=MicroPython]`_`f or `F33f`_`[CPython`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=CPython]`_`f using the Adafruit written Blinka compatibility layer.`:cite-ref-20[`F5bf`_`[20`#cite-note-20]`_`f] It acts as a translation layer between CircuitPython code and underlying code. This allows CircuitPython code to run on many more devices including a wide range of `F33f`_`[single-board computers`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Single-board_computer]`_`f which are listed on circuitpython.org.`:cite-ref-21[`F5bf`_`[21`#cite-note-21]`_`f] It is a `F33f`_`[pip`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Pip_(package_manager)]`_`f installable Python library.
