Raspberry Pi PoE HAT+ with Enhanced Isolated SMPS
Introduction
Raspberry Pi has introduced a new and improved PoE HAT+, which delivers almost twice the power of its predecessor. This upgrade enhances efficiency and performance, making it a valuable addition for Raspberry Pi users. In this blog, we will explore the features of the latest PoE HAT+, its specifications, and the key improvements it brings.
What is PoE HAT?
The Raspberry Pi PoE HAT is an add-on board designed for Raspberry Pi 3 Model B+ and later versions. It allows the Raspberry Pi to be powered through an Ethernet cable, provided that the network is equipped with power-sourcing equipment. Additionally, the PoE HAT includes a built-in fan to help cool the Raspberry Pi’s processor, improving thermal management.
Powering your Raspberry Pi over Ethernet offers several advantages, including reduced adapter costs and a cleaner, more streamlined setup.
Key Features of the New PoE HAT+
The latest PoE HAT+ maintains most of the specifications of the previous version, with one significant enhancement: an upgraded power supply transformer. This newly introduced isolated switched-mode power supply (SMPS) improves stability and efficiency. Furthermore, the output power has increased from 2.5A to 4A, making it better suited for Raspberry Pi 4, which operates on 15W power.
Specifications of PoE HAT+
- Standard: IEEE 802.3at-2003 PoE
- Input Voltage: 37–57V DC, Class 4 device
- Output Power: 5V DC/4A
- Cooling: 25mm × 25mm brushless fan delivering 2.2 CFM for enhanced processor cooling
- Features:
- Fully isolated switched-mode power supply (SMPS)
- Intelligent fan control for optimized cooling
- Operating Temperature: 0°C to +50°C
The comparison between the SMPS in the new and old PoE HAT shows a noticeable improvement in performance and efficiency.
Conclusion
The PoE HAT+ is a significant upgrade for Raspberry Pi users looking to power their devices over Ethernet. It not only delivers twice the power of its predecessor but also enhances stability with its new isolated SMPS design. By eliminating the need for an external adapter and additional cooling solutions, it offers a cost-effective and efficient solution for powering Raspberry Pi setups.
