// ESP8266-01 (blue) got too little storage space to work with WLED. 0.10.2 is the last release supporting this unit.

// ESP8266-01 (black) has 1MB flash and can thus fit the whole program, although OTA update is not possible. Use 1M(128K SPIFFS).
// 2-step OTA may still be possible: https://github.com/Aircoookie/WLED/issues/2040#issuecomment-981111096
// Uncomment some of the following lines to disable features:
// Alternatively, with platformio pass your chosen flags to your custom build target in platformio_override.ini

// You are required to disable over-the-air updates:
//#define WLED_DISABLE_OTA         // saves 14kb

// You can choose some of these features to disable:
//#define WLED_DISABLE_ALEXA       // saves 11kb
//#define WLED_DISABLE_BLYNK       // saves 6kb
//#define WLED_DISABLE_HUESYNC     // saves 4kb
//#define WLED_DISABLE_INFRARED    // there is no pin left for this on ESP8266-01, saves 12kb
