1, Supports Raspberry Pi 3B+ 4B. With the adapter module you can easily extend Raspberry-Pi projects to industrial control applications. And support 802.3 af Power-over-Ethernet (PoE) from Raspberry Pi gigabit ethernet port, allows you to power your Raspberry Pi using Power over Ethernetenabled networks.
2,
Power-over-Ethernet (PoE): IEEE 802.3 af compliant. Support PoE applications in both of Fast / Gigabit Ethernet environments. Fully isolated switched-mode power supply. Support wide input voltage range 37Vdc to 57Vdc. output 5V/ 2.5A 3, If you dont want to use PoE power supply, you can still use the Raspberry Pi USB power supply port to supply 5V power, the PoE circuit will not affect your USB power supply. BUT, you can only choose one of the two, and you cannot connect the two power supply modes at the same time, otherwise your Raspberry Pi module may will be damaged. 4, Terminal block with GPIO labels, pitch 3.5 mm/ 0.138", wire size range 26AWG to 16AWG, strip length 5mm, screw M2 steel, pin header and cage copper.
5,
Package included: 1x RPi PoE breakout board, 4x M 2.5 x16mm nylon standoffs, 4x M 2.5 x6mm nylon standoffs, 4x
M 2.5 nylon nuts (NOTE: the item not include Raspberry Pi module).
