ST takes flight on this STM32F405 #feather, now available at @digikey !

4382 09

Thanks to support from our friends at Digi-Key, we were able to bring the STM32F405 to the Feather line, and you can pick one up at at Digi-Key.com.

It 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
  • We use the built-in USB DFU bootloader to load firmware. It does not come with a
  • UF2 bootloader.

With CircuitPython basics running on this board, it’s fast to get all our drivers working, then use the built in plotter in Mu to instantly get sensor data displaying within 3 minutes of unboxing. Check out our learn guide here.

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.
