Image of Board

The Evo M51 is an FPGA-enhanced Feather compatible compute module from Alorium Technology that features a 32-bit SAMD51 microcontroller along with an Intel MAX 10 FPGA.

Designed for use as an embeddable system-on-module, all of the standard Feather I/O are also routed to castellated vias along the edge of the board. There are 34 additional castellated digital I/O connected to the FPGA and accessible via the SAMD51.

Most digital I/O connections are routed through the FPGA to and from the primary and castellated I/O. This provides the opportunity for developers to immediately capture inputs or drive outputs from the FPGA without requiring direct interaction with the SAMD controller.

Evo M51 will support Alorium Technology-supplied pre-built FPGA images that target specific application use cases. In addition, designers will have the option to develop their own custom logic blocks and integrate them into the top-level MAX 10 FPGA design.

Evo was specifically designed to support running CircuitPython. It is also programmable with Arduino just like many other boards based upon the SAMD51. So, writing and uploading firmware to the microcontroller is easy and familiar.

Evo M51 CircuitPython Library Bundle
In order to take full advantage of the additional I/O on Evo M51 using CircuitPython, we have created a custom library bundle that can be found on the Alorium Technology GitHub page:

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.
