Qwiic Micro without Flash

by SparkFun

Image of Board

The SparkFun Qwiic Micro is an 1 x 1 inch microcontroller made for the Qwiic Eco-system. It’s SparkFun’s smallest microcontroller to date that’s made for integrating into small projects. Onboard is the Atmel ATSAMD21E18 32-bit ARM Cortex-M0+ processor with 256KB flash, 32KB SRAM, and an operating speed of up to 48MHz.

  • 13 GPIO Pins - The SparkFun Qwiic Micro still has 13 GPIO pins, 5 of which are analog.
  • UF2 Bootloader - The SparkFun Qwiic Micro comes with the UF2 Bootloader which does not require the board to have drivers installed on modern operating systems. It also allows for easy drag and drop programming.
  • SWD Programming Header - On board is a four pin header for reprogramming the microcontroller for advanced users who want to modify the chip to their liking.
  • Optional Circuitry - There are pads for an extra flash memory chip in an SOIC 8-Pin Package. Check out SparkFun’s site for the specific chip used for the circuity python build that includes this chip!

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. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
