Octa2Go Setup Instructions
Your Octa2Go comes with WLED pre-installed and ready to use. These instructions walk you through first-time setup, safe power wiring, LED configuration, and connecting to your network. If you ever need to re-flash the firmware, download links are provided at the bottom of this page.
The Octa2Go supports 5V, 12V, or 24V pixels. Before connecting anything, ensure the voltage jumper on the board is set to match your power supply and the pixels attached to ports 1–4.
Connect the voltage and ground lines from your DC power supply to P1. The Voltage (V+) connects to the 5V–24V terminal and Ground (V-) connects to the GND terminal.
P1 powers the ESP32, expansion header, and ports 1–4. The voltage on P1 must match the pixels attached to ports 1–4.
You may connect the same or a different power supply to P2. P2 powers ports 5–8 only. There is no voltage jumper setting for P2, but the voltage on P2 must match the pixels attached to ports 5–8.
The reverse-protection circuit protects the controller only — any LEDs connected at the time may still be damaged. Always power on without pixels first to verify correct polarity.
Once connected correctly, the red LED on the ESP32 will light and the controller will begin booting WLED.
Remove the green male Phoenix connectors from the output ports. Insert the wires from your pixel strand into a connector, ensuring that Voltage (V), Data (D), and Ground (G) match the wiring diagram above.
On your phone or computer, open WiFi settings and look for a network named WLED-AP-Octa2Go. Connect to it — if prompted for a password, enter wled1234.
A browser window should open automatically with the WLED welcome screen. If it does not, open your browser and navigate to http://4.3.2.1
Setting a current limit prevents the controller from drawing more power than it can safely handle. Navigate to Config → LED & Hardware (called LED Preferences in versions older than 0.16).
Set Maximum PSU Current to 40000 mA (5A × 8 outputs). Then check the box labeled "Use per-output limiter" — this distributes the 40000mA evenly across all eight outputs, capping each at 5000mA.
Finally, set mA/LED to 30mA (typ, 12V) if you are using 12V bullet pixels. This improves WLED's current estimation accuracy.
Navigate to Config → WiFi Setup and enter your network SSID and password. Click Save & Connect, then wait a few seconds and refresh the page.
Once connected, your assigned IP address will appear above the Configure Access Point section. You can then access the Octa2Go directly via your browser by entering this IP in the URL bar.
The WLED mobile app makes it easy to discover and control your controller without needing to know its IP address. Tap + then Discover Lights to find your Octa2Go automatically.
By default, the Octa2Go is configured for 100 pixels on each of its eight outputs. When first powered on with pixels connected, they will display an amber/orange color — this is normal.
Most bullet pixels use an RGB color order, which is the default. If your colors don't display correctly, identify the correct color order using the method below.
- Set your lights to Red in WLED. Note the color that actually appears on the pixels.
- Set to Green. Note the color.
- Set to Blue. Note the color.
- The first letters of the three observed colors form your correct color order (e.g. Blue, Green, Red = BGR).
Navigate to Config → LED Preferences → Hardware Setup → LED Outputs → Color Order and update the setting for each output. Click Save when done.
Your Octa2Go comes with firmware pre-installed. If you ever need to re-flash, use our Web Flasher for the easiest experience, or download the files below for manual flashing.
