  🚀 Overview – Three Methods to Download Firmware

  There are three available methods for downloading and installing firmware for your WLED controller.

  ---

  🌐 Method 1 – Download the General WLED Firmware

  (Via the two official Web Installer websites)

  You can download and install the general WLED firmware using either of the following links:

  🔗 https://install.wled.me/
  🔗 https://wled-install.github.io/

  📥 What You Can Do With These Installers

  • Download the latest stable WLED firmware

  • Flash firmware directly in your browser (Chrome / Edge required)

  • No additional software needed

  • Automatically detects ESP8266 / ESP32 / ESP32-S3

  • Configure Wi-Fi & LED settings after install

  🧭 How to Use These Installers

  1. 🔌 Connect your WLED controller to your computer via USB

  2. 🌐 Open one of the Web Installer links

  3. ▶ Click “Install”

  4. 🖥 Select your device from the port list

  5. ⏳ Wait for the flashing process

  6. 📶 Configure Wi-Fi and LED settings

  ⚠️ Notes

  • These are universal WLED firmware builds—not model-specific.

  • For light systems requiring special timing or RGBW / RGBWY mapping, see
    👉 Method 3 – Model-Specific Firmware.

  🛠️ Method 2 – Flash the .BIN Firmware

  (Using ESP_Flash_Download_Tool or ESP-Flasher)

  This method lets you manually flash a .bin firmware file using professional flashing tools.

  Perfect for:

  • 🧩 Model-specific firmware

  • 🧪 Beta or custom builds

  • 🔧 Advanced users needing full control

  We recommend two applications:

  1. ESP_Flash_Download_Tool (official Espressif)

  2. ESP-Flasher (simple & cross-platform)

  Both are included in the attachments.

  📦 How to Flash Firmware Using These Tools

  🔽 Step 1 — Download the .BIN Firmware File

  You may download:

  • The universal WLED .bin

  • Model-specific firmware (for your light brand/model)

  • Custom firmware from the forum

  Make sure the firmware matches your chipset:

  • ESP32

  🔌 IO Pin Assignment (Our Controller Platform)

  The controller is based on an ESP32 platform with the following GPIO assignments.

  ---

  💡 1. LED Data Outputs

  Function	GPIO Pin	Description
  Data_GPIO_OUT1	GPIO2	Primary LED data output 1
  Data_GPIO_OUT2	GPIO15	Secondary LED data output 2

  Used as pixel LED data lines (WS281x, SM16703, SM16825, RGBW/RGBWY).

  ---

  🎛 2. Buttons

  Function	GPIO Pin	Description
  Button 0	GPIO0	User button 0
  Button 1	GPIO25	User button 1

  These can be mapped in WLED for power toggle, preset cycling, playlist control, etc.

  🎤 3. Microphone Interface (Generic I2S PDM)

  • I2S SD (Data In): GPIO35

  • I2S WS (LRCLK): GPIO27

  • I2S SCK (Clock): unused

  In summary:

  The microphone uses a PDM I2S input, with SD on GPIO35 and WS on GPIO27.
  The I2S SCK pin is not used in this design.
