After using it for a while, I wanted to share my insights to help you decide if this is the right accessory for your Pi projects. Here’s what I learned during my experience.
What Is the Geeekpi Isolated POE Hat?
The Geeekpi Isolated POE Hat is an add-on board designed specifically for Raspberry Pi 4 (45-pin). It enables your Pi to receive power and network connectivity through a single Ethernet cable using PoE technology. What makes this hat stand out is its isolated power design, which helps protect your Pi from electrical surges and noise, ensuring stable operation.
Why I Chose an Isolated POE Hat
I wanted to keep my Raspberry Pi setup clean and reduce cable clutter, so powering via Ethernet sounded ideal. The isolation feature was a big plus for me because it adds an extra layer of protection — especially important if you’re running your Pi in an environment with fluctuating power or industrial equipment nearby.
Key Features to Consider
- Compatibility: This PoE hat is made for the Raspberry Pi 4 with the 45-pin header. Make sure your Pi model matches.
- Power Output: It can deliver up to 15.4W of power, which is sufficient for the Pi and many attached peripherals.
- Isolated Power Design: Prevents ground loops and reduces noise, which can improve reliability.
- Easy Installation: It plugs directly onto the Raspberry Pi’s GPIO header without soldering.
- Cooling: Includes a small fan that activates under load, helping to keep your Pi cool during heavy use.
