Feather ESP32-C6 4MB Flash No PSRAM
by Adafruit
The ESP32-C6 is Espressif’s first Wi-Fi 6 SoC integrating 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It brings the goodness you know from the low-cost C3 series and improves it with Zigbee/802.15.4 at 2.4Ghz. That means it could make for great Matter development hardware!
We took our Feather ESP32-S2 and swapped out the ‘S2 for a C6. Plus some re-routing and here’s what we’ve got: a C6 Feather with lots of GPIO, lipoly charging and monitoring with the MAX17048, NeoPixel, I2C Stemma QT port, and a second low-quiescent LDO for disabling the I2C and NeoPixel when we want ultra-low power usage - as low as 17uA in deep sleep.
One thing to watch for is that, like the C3, the C6 does not have native USB. It does have a ‘built in’ USB Serial core that can be used for debugging, but it cannot act like a mouse, keyboard, or disk drive. That means if you are running CircuitPython you will need to use WiFi, Bluetooth or WebSerial for transferring files back and forth rather than drag-and-dropping to a drive. Ditto for the bootloader side, this chip cannot run UF2.

CircuitPython 9.2.0-beta.1
This is the latest development release of CircuitPython that will work with the Feather ESP32-C6 4MB Flash No PSRAM.
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.
