POE

The Luckfox Lume board provides an H1 PoE expansion header. With a compatible PoE module installed, power can be received over an Ethernet cable through the PoE-capable RJ45 port. The module converts it to 5V and supplies the board through VCC-5V-SYS and GND on H1, allowing one Ethernet cable to carry both network data and power.

1. Specifications​

ItemDescription
Luckfox Lume PoE interfaceOnboard H1, 2.54 mm pitch, 6 pins
PoE standardIEEE 802.3af; requires a compatible powered-device module
PoE input voltageRefer to the rated input range of the selected compatible module
Module output voltage5V DC

2. Usage​

  1. Prepare the following:

    • Luckfox Lume board;
    • A PoE module with a 5V output that matches the Lume H1 pinout and mounting orientation;
    • A PoE switch or injector that supports IEEE 802.3af powered devices;
    • An eight-conductor Cat5e or higher-category Ethernet cable.

  2. Install the PoE module:

    • Disconnect all power connections, including Type-C, the 40-pin header, and Ethernet.
    • Check the orientation against the H1 pinout and module silkscreen, then install and secure the module.
    • Confirm that the module's 5V output connects to H1 pin 5 and GND connects to pin 6.

  3. Connect and power on:

    • Connect one end of the Ethernet cable to a powered port on the PoE switch and the other to the Lume PoE port routed to H1. Do not assume that both Ethernet ports can receive power.
    • Enable power on the switch port and check the board's power and Ethernet indicators.
    • The board should boot and establish an Ethernet link. Once it obtains an IP address, you can log in over SSH.

H1 is not a complete PoE powered-device circuit and must be used with a compatible module. Never connect the high PoE voltage from the Ethernet cable directly to the 5V power pin. Unless simultaneous power inputs are explicitly supported, do not connect PoE, Type-C, and 40-pin header power at the same time.
