This compact and reliable NANO board is built around the NINA B306 module, based on Nordic nRF 52840 and containing a powerful Cortex M4F. Its architecture, fully compatible with Arduino IDE Online and Offline, has a 9 axis Inertial Measurement Unit (IMU) and a reduced power consumption compared to other same size boards. This allows the design of wearable devices and movement sensing projects that need to communicate to other devices at a close range. Arduino NANO 33 BLE is also ideal for automation projects thanks to the multiprotocol BT 5.0 radio.

This is the latest unstable release of CircuitPython that will work with the NANO 33 BLE.
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 it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.
All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
