  • You will need PSE (Power Supply Equipment) to supply PoE signal to the Raspberry Pi, such as a PoE switch or injector.
  • This HAT only supports CAT 5Eand CAT 6E network cable.
  • A network switch or power supply equipment (PSE) is required to provide PoE signals, and they must comply with IEEE 802.3af or 802.3at PoE standards, especially section 33.4.1 on PSE electrical isolation. For non-isolated switches, such as some Ubiquiti switches cannot provide proper isolation, they can only be used with CAT 5E and CAT 6E network cables.
