CircuitPython 9.2.1
This is the latest stable release of CircuitPython that will work with the ARAMCON Badge 2019.
Use this release if you are new to CircuitPython.
On nRF boards, CircuitPython 8.2.0 and later require UF2 bootloader version 0.6.1 or later. Older bootloaders cannot load the firmware. See Update UF2 Bootloader below.
Built-in modules available: _asyncio, _bleio, adafruit_bus_device, adafruit_pixelbuf, aesio, alarm, analogio, array, atexit, audiobusio, audiocore, audiomixer, audiomp3, audiopwmio, binascii, bitbangio, bitmapfilter, bitmaptools, board, builtins, builtins.pow3, busdisplay, busio, busio.SPI, busio.UART, codeop, collections, countio, digitalio, displayio, epaperdisplay, errno, fontio, fourwire, framebufferio, getpass, gifio, i2cdisplaybus, io, jpegio, json, keypad, keypad.KeyMatrix, keypad.Keys, keypad.ShiftRegisterKeys, keypad_demux, keypad_demux.DemuxKeyMatrix, locale, math, memorymap, microcontroller, msgpack, neopixel_write, nvm, onewireio, os, os.getenv, paralleldisplaybus, pulseio, pwmio, rainbowio, random, re, rgbmatrix, rotaryio, rtc, sdcardio, select, sharpdisplay, storage, struct, supervisor, synthio, sys, terminalio, time, touchio, traceback, ulab, usb_cdc, usb_hid, usb_midi, vectorio, warnings, watchdog, zlib

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.
Update UF2 Bootloader
Latest version: 0.9.2
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.).
It is not necessary to update your bootloader if it is working fine. Read the release notes on GitHub to see what has been changed. In general, we recommend you not update the bootloader unless you know there is a problem with it or a support person has asked you to try updating it.
On nRF boards, CircuitPython 8.2.0 and later require UF2 bootloader version 0.6.1 or later. Older bootloaders cannot load the firmware. To check the version of your board's bootloader, look at INFO_UF2.TXT when the BOOT drive is present. To update the bootloader, refer to the "Update Bootloader" page in the guide for your board, or start with this page.
After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
