When using an ESP8266 board, it's recommended to use pins GPIO1, GPIO2, or GPIO3 for LED Data using other pins will require bit-banging and may cause slow performance and/or issues elsewhere (such as with IR decoding). Please note that these are GPIO numbers, please consult a pinout for your board to find the labeled pin (e.g D4 = GPIO2 on most ESP8266 boards). Use a WiFi device to connect to the access point WLED-AP using the default password wled1234.Īll pins can be changed in the Hardware section of LED settings. If everything worked the first thirty LEDs will light up in bright orange to stimulate courage, friendliness and success!ģ. I want to modify WLED (compile from source code) I just want to use WLED! (install release binary) Flash the software to your ESP module! There are two options for this step:

Recommend is to use GPIO1 (TxD) for clock and GPIO2 (D4) for data.įor safe operation it is recommended to size your power wires correctly and to integrate fuses.įor reference, you may use this LED power, wiring and fuse calculator.įor analog LEDs, the MOSFETs IRLZ44N or STP55NF06L are good candidates. software SPI: since all pins can be changed in the Hardware section of LED settings, you can use any pins. hardware SPI: use GPIO14 (SCLK) for clock and GPIO13 (MOSI) for data. While using an ESP8266 and LEDs that have clock and data, you can either use hardware SPI (mostly faster) or software SPI. Make sure to connect ESP and LED-strip grounds together!

Please use the board pinout from the specific board you purchased and use the GPIO PINS to reference this guide. Note: Board pin naming varies depending on the manufacturer. Optionally connect a normally open pushbutton to GPIO0 (NodeMCU/Wemos pin D3, on ESP32 use IO17) and ground for configurable actions. If the connecting wire cannot be kept short, use a level shifter/translator. On most ESP8266 based development boards this pin is labeled D4, on ESP32 based boards use IO16 or G16 or 16.

Connect a WS2812B-compatible RGB(W) led strip to GPIO2. Unless noted otherwise, all information applies to the latest release (v0.13.3).
