The SparkFun MicroMod STM32 Processor Board is ready to rock your MicroMod world with its ARM® Cortex®-M4 32-bit RISC core! This little Processor Board provides you with an economical and easy to use development platform if you’re needing more power with minimal working space. With the M.2 MicroMod connector, connecting your STM32 Processor is a breeze. Simply match up the key on your processor’s beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all Carrier Boards). The STM32 is one of the most powerful and economical microcontrollers available so to be able to add it to your MicroMod Carrier Board is a huge advantage for your project!

As we previously stated; the STM32F405 Processor is based on the high-performance ARM® Cortex®-M4 32-bit RISC core and can operate at a frequency of up to 168 MHz. This core features a floating point unit (FPU) single precision which supports all ARM single precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. This Processor Board utilizes the DFU bootloader for uploading code, and incorporates an extensive range of enhanced I/Os and peripherals. To complement the STM32F405 processor, we’ve also added an additional 128Mb (16MB) serial flash memory chip to the underside of the board.

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. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
