# Hardware Assembly The cable connections between all parts of the system are shown in the schematic below. ![Wiring schematic of the SENSORhub SEH controller with LED strips connected to the LED strip channels and a PoE switch connected to the RJ45 port](./images/seh-cabling-schematic.png) Each LED strip connects to one of the LED strip channels (outputs 1–5). The strip conductors are: `GND` (blue), `Data` (black) and `+5V` (brown). ## Power Supply Power can be supplied through PoE or USB. The internal PoE converter is limited to 4 W. Typical consumption:

Component	Power consumption
Controller	1 W
Lit LED strip	3 W per meter
SMC button (SENSORswitch)	0.8 W each

:::note When using 4 m or 5 m LED strips and/or more than 2 SMC buttons, it is recommended to use USB or an external PoE splitter with a higher wattage (for example the joy-it SBC-POE-POWER-C with 10 W). :::
