Install WLED binary

What binary should I use?

I would recommend to always use the latest release. Please use the following binary for these boards respectively:

Binary Name	For devices
WLED_0.x.x_ESP8266.bin	NodeMCU, Wemos D1 mini, ESP-12, all ESP8266 with 4Mb flash. Recommended.
WLED_0.x.x_ESP32.bin	All ESP32 devices (try this if the WLED-AP doesn't appear after flashing)
WLED_0.x.x_ESP8266_1M_ota.bin	ESP-01 (black PCB), most Sonoff devices, ESP8265, all ESP8266 with 1Mb flash. This binary has some interfaces disabled (Alexa, Blynk, Hue sync, Infrared) in order for wireless updates to continue working.
WLED_0.x.x_ESP8266_1M_full.bin	ESP-01 (black PCB), most Sonoff devices, ESP8265, all ESP8266 with 1Mb flash. This binary has the full feature set, but wireless updates will not work.
WLED_0.x.x_ESP8266_512k.bin	ESP-01 (blue PCB), older Sonoff devices, all ESP8266 with 512k flash. Interfaces (Alexa, Blynk, Hue sync, Infrared) disabled, no OTA. Support will not be possible in future versions.
WLED_0.x.x_ESP8266_ledpinY.bin	Custom build for 4Mb flash ESP8266 and WS2812b. LED pin is changed (default is GPIO2). LED pin 4 is useful for the QuinLed Dig Uno board.
WLED_0.x.x_ESP8266_apa102.bin	Custom build for 4Mb flash ESP8266 and APA102 LEDs (clock pin GPIO0, data GPIO2).
WLED_0.x.x_ESP8266_ws2801.bin	Custom build for 4Mb flash ESP8266 and WS2801 LEDs (clock pin GPIO0, data GPIO2).
WLED_0.x.x_ESP32_ledpinY.bin	Custom build for ESP32 and WS2812b. LED pin is changed (default is GPIO2). LED pin 16 is useful for the QuinLed Dig Uno board.
esp32_bootloader.bin	Not a WLED release. Can be flashed to a brand new ESP32 before flashing the WLED binary itself.
