SparkFun Qwiic Micro with 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 it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.

Past Releases

All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
