Introducing MicroDev microC3 dev-board based on Espressif’s ESP32-C3 SoC, which is equipped with a RISC-V 32-bit single-core processor, operating frequency up to 160 MHz, supports secondary development without using other microcontrollers or processors. The ESP32-C3 is an highly integrated low power Wi-Fi and Bluetooth system-level chip (SoC), designed for various applications such as internet of things (IoT), mobile devices, wearable electronics, smart home, etc.

This is the latest unstable release of CircuitPython that will work with the MicroDev microC3.
Unstable builds have the latest features but are more likely to have critical bugs.

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. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
