Wiring up a Dig-Next-2 is a five-step job: pick a supply, power the board, connect a strip, set up WLED, and dial in your LEDs. Here is the basic single-strip setup, start to finish. Got a specific question? The FAQ has the details.

The whole picture: supply in, LEDs out. Match the supply voltage to your strip.
Start with the power supply, because it sets everything else. Match its voltage to your LED strip: a 5V supply for 5V strips, 24V for 24V strips, and so on. Then size the wattage to your LEDs, roughly 0.3W per RGB pixel at full white, with some headroom on top. For something that runs all day, a good current-limited supply is the one part worth not cutting corners on. The power-handling guide covers how to size it.
The Dig-Next-2 auto-senses anything from 5V to 48V, so the only number that has to match is your strip's voltage.
Connect the supply to the Main Input terminals: ground to GND, positive to +. The input is reverse-polarity protected, so a slip will not fry the board, but it is worth getting right the first time. Tighten the screw terminals onto clean, twisted wire ends, and keep the supply unplugged from the wall until everything is connected.
You will know it is right when the wire colors match the labels on the orange input block and a gentle tug does not move them.
Your strip has three pads: ground, data-in (often marked DI or DIN), and power. Wire them to one controller output in this order from the top: GND, Data, then V+. Powering the strip from a fused output means a short trips a cheap fuse instead of your strip.
Check the little arrows printed on the strip. They must point away from the controller, and Data always goes to the input end of the strip, never the middle.
Most boards arrive already running WLED. If yours needs it, or you want a clean start, plug in USB-C and open install.quinled.info/dig-next-2/ in a Chrome-based browser to flash it. Then power it up, join the WLED-AP Wi-Fi network from your phone, open the setup page, and add your home Wi-Fi. You will know it worked when WLED-AP shows up in your Wi-Fi list, and after setup, when the WLED dashboard loads in your browser.
ESP32 boards use 2.4GHz Wi-Fi, not 5GHz. Make sure your phone is on the 2.4GHz band during setup.
In WLED's LED settings, set how many LEDs you have, the strip type (for example WS2812B or SK6812 RGBW), and the color order. Save, and your strip should light up. From there, pick colors, effects and palettes, and save your favorites as presets you can recall in a tap.
Wrong colors or no clean white almost always means the strip type is set to RGB when your strip is RGBW. Switch it and they snap into place.
Before the power supply goes into the wall, run down this list once. It catches nearly every first-build mistake:
One controller, one power supply, two independent strips. Wire each strip to its own data output and feed both from the controller's fused power outputs. Each strip then gets its own length, chip type and effects in WLED.
Two strips from one Dig-Next-2: each on its own data output, both powered from the single supply.
On a long run the far end dims and whites tint, which is normal voltage drop rather than a fault. Feed power to the strip again partway along or at the far end, using one of the controller's spare power outputs, and the whole run evens out. The power-handling guide covers how much and where.
There is a microphone on board, so enabling WLED's AudioReactive usermod gets your lights moving to music with no extra parts. The button inputs, I²C port and QEXP header are there for physical switches, sensors and other add-ons whenever you want to grow the build.
