Image of Board

The EFR32xG24 Explorer Kit is an ultra-low-cost, small form factor development and evaluation platform for the EFR32MG24 Wireless Gecko System-on-Chip.

The EFR32xG24 Explorer Kit is focused on rapid prototyping and concept creation of IoT applications. It is designed around the EFR32MG24 SoC, which is an ideal device family for developing energy-friendly connected IoT applications.

Key features of the board includes a USB interface, an on-board SEGGER J-Link debugger, Packet Trace Interface, push buttons, and support for hardware add-on boards via a mikroBus socket and a Qwiic® connector. The hardware add-on support allows developers to create and prototype applications using a virtually endless combination of off-the-shelf boards from mikroE, sparkfun, AdaFruit, and Seeed Studios.

CircuitPython 9.1.0-beta.3

This is the latest development release of CircuitPython that will work with the EFR32xG24 Explorer Kit.

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.
