Power Over Ethernet HAT For Raspberry Pi 4/3B+ - PoE Board With OLED Display & Cooling Fan

About This Product

Raspberry Pi enthusiasts, this Power Over Ethernet HAT is seriously slick for cleaning up your setup! It lets you power your Raspberry Pi 3B+ or 4B directly through the Ethernet cable - no more separate power adapter cluttering your workspace. The 802.3af compliance means it works with standard PoE network equipment, so you just need a PoE switch or injector to get everything running. The built-in 0.91-inch OLED display is super handy for monitoring your Pi's status in real-time - you can see processor temperature, IP address, and fan status at a glance without needing to SSH in. Speaking of the fan, it's programmable and can be set to auto-run on power-up or controlled based on temperature thresholds via a simple switch. The cooling is effective and quiet, keeping your Pi running optimally during heavy processing tasks. The standard 40-pin GPIO header is stackable, so you can still use other HATs if needed. It integrates a PCF8574 IO expander for I2C bus, giving you pin P0 for direct fan control plus additional spare IO pins for other projects. The power input handles 37V to 57V DC from your PoE source and outputs a solid 5V 2.5A to your Pi - plenty of power for most applications. Installation is straightforward, and the included standoffs make mounting secure. Perfect for network-attached projects, IoT devices, digital signage, or any situation where you want a clean single-cable solution for both power and data. The build quality feels premium, and having both cooling and status monitoring built into one HAT is incredibly convenient. If you're tired of power cable clutter or building projects that need to be placed away from power outlets, this PoE HAT delivers a professional, integrated solution that just works. Seriously, once you go PoE with your Raspberry Pi projects, you'll wonder why you ever messed with separate power adapters!
