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.

CircuitPython 7.0.0-rc.3

This is the latest unstable release of CircuitPython that will work with the MicroMod STM32 Processor.

Unstable builds have the latest features but are more likely to have critical bugs.

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.
