              • Get hands-on familiarity with the NetBurner platform by studying, building, and modifying ample source code examples.
              • Device applications can be written in C/C++ (or assembly language).
              • Includes Eclipse based IDE with graphical debugger. If you prefer using the command line, we include several source code examples with makefiles.
              • Includes royalty-free TCP/IP Stack, web server, Real-time OS (RTOS), and more. Although our software stack has a small memory footprint, you can include only what you need to free up additional memory or processing power.
