Challenger RP2040 LTE by Invector Labs
The Challenger RP2040 LTE is an Arduino/CircuitPython compatible Adafruit Feather format microcontroller board based on the Raspberry Pico chip.
This board has been designed with portable applications in mind. By using the powerful dual core RP2040 combined with 8Mbyte of flash memory, you get a device that can handle pretty much anything you can throw at it. For instance, if you let one core handle the LTE modem and the second core do all the UI stuff, you get an extremely responsive system. Not to mention that the 8 MByte of FLASH memory will let you install any (or all) CircuitPython support libraries that you will ever need.

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.
