The PoE HAT
The Raspberry Pi Power over Ethernet HAT is a small accessory for the Raspberry Pi computer. It can only be used with the Raspberry Pi 3 Model B+ (launched March 2018). The PoE HAT allows you to power your Raspberry Pi using Power over Ethernet–enabled networks; for this product to be used, the network it is connected to needs to have power-sourcing equipment installed.
Supplied with this product
- Raspberry Pi PoE HAT
- Mechanical spacers
Other hardware needed
- A Raspberry Pi 3 Model B+
- An Ethernet cable
- Power-sourcing equipment for a 802.3af Power over Ethernet network
Connecting your PoE HAT to the Raspberry Pi
- Before installing the PoE HAT, you must attach the supplied spacers in the four corners of the board
- Then connect the Raspberry Pi PoE HAT to the two 0.1” headers (40 + 4) that are fitted on the Raspberry Pi
- Once the PoE HAT board is connected, you can power the Raspberry Pi through its RJ45 network connector
Disconnecting your PoE HAT
- Take care when separating the HAT from the Pi
- Pull evenly so that it detaches from all the pins at the same rate; do not pull one end of the connector off before the other
Additional information
No modification to the main Raspberry Pi board is needed for this product to work. Please ensure that your Raspberry Pi’s software is up to date for all functionality to be available. The PoE HAT is fitted with a small fan that is controlled by the Raspberry Pi via I2C. The fan will turn on and off automatically depending on the temperature of the main processor on the Raspberry Pi.
不覺失笑，難到也想作『飛行派』耶？
事恐不妙！
轉眼已將過兩年，仍在異地樂逍遙？
辛勞不念也罷了，銀子可是不該少！
