by Luatos

Image of Board

The LuatOS ESP32-C3 core board is a type of development board based on the ESP32-C3 chip, which is a highly integrated Wi-Fi and Bluetooth system-on-chip (SoC) designed for low-power Internet of Things (IoT) applications.

The LuatOS ESP32-C3 core board is designed to help developers prototype and develop their IoT projects quickly and easily. It includes a variety of hardware features, such as a USB Type-C and CH343 USB-UART for power and programming.

The board is also equipped with LuatOS, which is an open-source operating system that provides a high-level API for developers to interact with the board’s hardware and peripherals. LuatOS is based on the Lua programming language, which is known for its simplicity and ease of use, making it a popular choice among developers.

Overall, the LuatOS ESP32-C3 core board Development Board is a powerful and versatile development tool that enables developers to quickly prototype and develop their IoT projects using the ESP32-C3 chip and LuatOS operating system.

CircuitPython 9.0.0-alpha.5

This is the latest development release of CircuitPython that will work with the Luatos ESP32-C3 Core Board – CH343 USB UART.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
