Introducing the microS2 - An ESP32-S2 based development board in the size of an esp32 module!

With Wi-Fi, native USB and a load of Flash & PSRAM the microS2 is perfect for use with CircuitPython while keeping the form-factor small.

Features & Specifications

  • ESP32-S2 32-bit 240MHz Tensilica processor - the next generation of ESP32
  • 16MB Flash & 8MB PSRAM - you can have huge data buffers
  • 2.4 GHz Wi-Fi 802.11b/g/n - get communicating with the world
  • All pins exposed & breadboard compatible - too good to be true
  • Neopixel (IO33) Blue led (IO21) - who doesn’t love some lights
  • Reset & Boot buttons - can also be used as user button
  • USB micro-B & QWIIC/STEMMA connector - easily connect with peripherals
  • 31 x 18 mm - all of the above in a small form factor

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.
