CircuitPython provides an approachable and logical means of conducting science with hardware. Paired with low-cost hardware shown to work in space, we can enable an new generation to question and explore the unknown. With the necessary “satellite stuff” already baked in, students can spend their time trying something new rather than reinventing the wheel (similar philosophy to early Arduino efforts and the microcontroller movement in general).

This is the latest stable release of CircuitPython that will work with the KickSat Sprite.
Use this release if you are new to CircuitPython.
Built-in modules available: _asyncio, adafruit_bus_device, adafruit_pixelbuf, alarm, analogio, array, atexit, binascii, bitbangio, board, builtins, builtins.pow3, busio, busio.SPI, busio.UART, collections, countio, digitalio, errno, frequencyio, i2ctarget, io, json, math, microcontroller, neopixel_write, nvm, onewireio, os, os.getenv, pulseio, pwmio, random, re, rtc, samd, sdcardio, select, storage, struct, supervisor, sys, time, traceback, usb_cdc, watchdog, zlib
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: v3.15.0
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.).
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.
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. After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
