 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 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.
