Image of Board

In the F401 series, the chip is the cheapest, even cheaper than some F1, and crushed F1 on the main frequency, and has a floating-point arithmetic module, the IO port contains all the basic functions. Therefore, it is possible to provide a learning platform with a very high cost performance for beginners. In practical applications, it is not because the computing power is insufficient, and the IO port is incomplete and hinders development.

  • 25MHZ high speed crystal oscillator & 32.768Khz 6PF low speed crystal oscillator
  • Flash pads are reserved, providing USBDisk&&FATFFS routines
  • Jumper cap can be used directly without installation.BOOT0 internal 10K resistance pull-down
  • Factory has burned breathing lamp &&USBCDC test procedures.
  • Provide available MicroPython firmware, configuration files
  • Adjust the direction of the jumping cap if it cannot be installed.Because the jump cap is wide on one side and narrow on the other.
  • V1.3 board with 3 buttons: reset key, BOOT0 key and user button.

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.
