COMING SOON – Adafruit Feather STM32F405 Express


Coming soon! Sign up to be notified when it’s in stock!

ST takes flight in this upcoming Feather board. The new STM32F405 Feather (video) that we designed runs CircuitPython at a blistering 168MHz – our fastest CircuitPython board ever! We put a STEMMA QT / Qwiic port on the end, so you can really easily plug and play I2C sensors.

This Feather has lots of goodies:

  • STM32F405 Cortex M4 with 1MB Flash, 168MHz speed
  • 3.3V logic, but almost all pins are 5V compliant!
  • USB C power and data – our first USB C Feather!
  • LiPo connector and charger
  • SD socket on the bottom, connected to SDIO port
  • 2 MB SPI Flash chip
  • Built in NeoPixel indicator
  • I2C, UART, GPIO, ADCs, DACs
  • Qwiic/STEMMA-QT connector for fast I2C connectivity

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
