  • Superb performance and memory usage (Sming compiles to native firmware!)
  • Fast and user friendly development
  • Simple yet powerful hardware API wrappers
  • Compatible with standard Libraries - use any popular hardware in few lines of code
  • Built-in file system: SPIFFS for Sming
  • Built-in powerful wireless modules
  • Powerful asynchronous (async) network stack.

  • Out of the box support for OTA over HTTPS.
  • ESP8266 specific features
