      <b>Home Assistant Yellow</b><br>
      This flagship version of Home Assistant Yellow is ready to go out of the box.
      <br><br>
      It comes pre-assembled in a custom enclosure with a Raspberry Pi Compute Module 4 (CM4) and a custom heat sink for fanless, silent operation. The CM4 is a version without wireless and has 2 GB RAM and 16 GB eMMC storage, pre-installed with Home Assistant.
      <br><br>
      All you need to get started is to plug in the power supply and the Ethernet cable, both of which are included. This variant does not have Power-over-Ethernet.

      <a href="https://yellow.home-assistant.io/poe/">Some assembly required!</a> This kit supports Power-over-Ethernet (PoE) and includes everything in the flagship version except the Raspberry Pi Compute Module 4.
      <br><br>
      Custom enclosure, custom heat sink, and Ethernet cable included. You must provide your own Raspberry Pi Compute Module 4 and install Home Assistant on it. The kit does not include a power supply (because power comes from PoE).
