  // ESP8266-01 (blue) got too little storage space to work with all features of WLED. To use it, you must use ESP8266 Arduino Core v2.4.2 and the setting 512K(No SPIFFS).
  
  // ESP8266-01 (black) has 1MB flash and can thus fit the whole program. Use 1M(64K SPIFFS).
  // Uncomment some of the following lines to disable features to compile for ESP8266-01 (max flash size 434kB):
  // Alternatively, with platformio pass your chosen flags to your custom build target in platformio.ini.override
  
  // You are required to disable over-the-air updates:
  //#define WLED_DISABLE_OTA         // saves 14kb
  
  // You need to choose some of these features to disable:
  //#define WLED_DISABLE_ALEXA       // saves 11kb
  //#define WLED_DISABLE_BLYNK       // saves 6kb
  //#define WLED_DISABLE_CRONIXIE    // saves 3kb
  //#define WLED_DISABLE_HUESYNC     // saves 4kb
  //#define WLED_DISABLE_INFRARED    // there is no pin left for this on ESP8266-01, saves 12kb
