The miniature (13mm x 44mm) Sigfox development kit (DVK), DVK-SFUS-1-GEVK, allows designers to quickly develop Sigfox connected applications in the RCZ2 region using the AX-SFUS-API SoC solution. The DVK comes with a free two-year Sigfox subscription and is pre-programmed with the Sigfox stack and an example application that can be used as-is or extended. Approximately 40kB of FLASH is available for application code. Included in the kit is the AXDBG-2-GEVK debugger used for debugging software and programming the FLASH. To program the DVK, the designer needs to download the development tools and the API software library (link below in the Technical Documents table).
