Power Over Ethernet HAT (Type B) For Raspberry Pi 3B+/4B, 802.3af Power-Sourcing Equipment Required

POE HAT for Raspberry Pi

Power Over Ethernet HAT for Raspberry Pi 3B+/4B, 802.3af-compliant(any backward-compatible future versions will be supported as well)

OLED for real-time monitoring temperature, IP, and fan status

The PoE HAT (B) is a 802.3af-compliant Power Over Ethernet accessory for the Raspberry Pi 3B+/4B. By using this small HAT and some proper 802.3af-compliant power sourcing equipments, it is possible to provide both network connection and power supply for your Raspberry Pi in only one Ethernet cable.

Features at a glance

• Standard Raspberry Pi 40PIN GPIO header, supports Raspberry Pi 3B+/4B
• PoE (Power Over Ethernet) capability，802.3af-compliant
• Fully isolated switched-mode power supply (SMPS)
• 0.91" OLED, for monitoring processor temperature, IP address, and fan status in real-time
• Onboard cooling fan, allows auto running on powerup OR programmable control, configured by switch
• Integrates PCF8574 IO expander for I2C bus, providing pin P0 for directly fan control, and more spare IO pins
