CircuitPython

CircuitPython is an open-source derivative of the MicroPython programming language targeted toward students and beginners. Development of CircuitPython is supported by Adafruit Industries. It is a software implementation of the Python 3 programming language, written in C. It has been ported to run on several modern microcontrollers.
CircuitPython is a full Python compiler and runtime that runs on the microcontroller hardware. The user is presented with an interactive prompt (the REPL) 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 Adafruit-compatible products as well as higher-level libraries for beginners.
CircuitPython is a fork of MicroPython, originally created by Damien George. The MicroPython community continues to discuss forks of MicroPython into variants such as CircuitPython.
CircuitPython is targeted to be compliant with CPython, the reference implementation of the Python programming language. Programs written for CircuitPython-compatible boards may not run unmodified on other platforms such as the Raspberry Pi.
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, handheld video game devices. Developer Chris Young has ported his infrared transmit-and-receive software to CircuitPython to provide interactivity and to aid those with accessibility issues.
Community.
The user community support includes a Discord chat room and product support forums. A Twitter account dedicated to CircuitPython news was established in 2018.
Availability.
The version 6.2.0 supports Atmel SAMD21 and SAMD51 microcontrollers from Microchip Technology, nRF52833 and nRF52840 from Nordic Semiconductor, CXD5602 (Spresense) from Sony, and STM32 F4-series from STMicroelectronics. Previous versions supported the ESP8266 microcontroller, but its support was dropped in version 4.
