The built-in 5V DC-DC converter is only rated up to 5A, limiting the total maximum output to 25W.
This means you can power up to 5 m of WS2812b 30 LEDs/m strip at full brightness.
For more, limit the brightness in WLED, or use multiple boards and chain them.
For more LEDs, limit the brightness in WLED, or use multiple boards and chain them.
The spring loaded terminals are only rated for 2A, with a maximum wire size of AWG 20.
If you intend to draw more current, you can add a connection to another 5V output from the LEDs or power port.
This is particularly relevant for re-injecting power, which you should do minimum every 5 meters.
If you need even more current, or use thicker cables, just solder the cable directly to the pins on the bottom or on the rear tab of the barrel jack connector.
If you need more than 5A, you are exceeding the use case of this board.
Switch back to using a external power supply and connect the LED strips directly to it.
You can even power the board with the same 5V or 8-36V power supply using the power port.
