Arduino NANO 33 IoT board has been designed to offer a practical and cost effective solution for makers seeking to add Wi-Fi connectivity to their projects (using Arduino) with minimal previous experience in networking. Learn how to set up the programming environment and get the hardware up and running, ready for your projects, in minutes.
WiFi is not supported. The LSM9DS6 and ATECC chips are supported in CircuitPython by libraries that may use more RAM than is available on the SAMD21.

This is the latest stable release of CircuitPython that will work with the NANO 33 IoT.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the NANO 33 IoT.
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.
Latest version: v3.10.0
The bootloader allows you to load CircuitPython, Makecode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).
To update, first save the contents of CIRCUITPY, just in case. Then double-click the reset button to show the BOOT drive. Drag the update-bootloader .uf2 file to the BOOT drive. Wait a few tens of seconds for the bootloader to update; the BOOT drive will reappear. Check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
