MCDODO PoE HAT for Raspberry Pi 4 & 3B+ Professional Isolated 3KV

Professional Isolated 3KV PoE HAT

This HAT adds Power-over-Ethernet to Raspberry Pi 4 Model B and Raspberry Pi 3 Model B+ boards. It accepts power from IEEE 802.3 af, IEEE 802.3 at and Passive DC 48V sources. The professional model provides galvanic isolation up to 3KV for use with non-compliant switches and injectors. It simplifies deployments by removing the need for individual power adapters.

Builders running clusters or remote nodes

Suits anyone powering multiple boards from a single PoE switch to reduce cabling and adapter count. The isolation protects hardware when the PSE side lacks its own isolation. Not for users without a PoE switch or injector, or those needing a standard power supply. Buyers who want a HAT without active cooling requirements should look elsewhere.

Galvanic isolation up to 3KV

This is the specification that determines suitability for industrial or mixed-voltage environments. It ensures the Pi side remains electrically separated from the Ethernet power source. Without this rating, non-compliant PoE equipment can damage the board. Verify your switch or injector matches the supported IEEE 802.3 af, IEEE 802.3 at or Passive DC 48V standards.
