What PoE splitter is recommended for powering Raspberry Pi devices

  Using a PoE splitter to power a Raspberry Pi is an efficient way to simplify wiring, especially in networked and remote setups. Since Raspberry Pi boards do not support PoE natively, a PoE splitter is required to separate power and data from an Ethernet cable, providing the appropriate voltage and current for the device.   Key Factors When Choosing a PoE Splitter for Raspberry Pi 1. Power Requirements of Raspberry Pi Models Different Raspberry Pi models have different power consumption needs. Choosing a PoE splitter that provides sufficient voltage and current is crucial for stable performance. Raspberry Pi Model Power Requirement Recommended Splitter Output Raspberry Pi 3B / 3B+ 5V / 2.5A (12.5W) 5V / 2.5A Raspberry Pi 4B (2GB, 4GB, 8GB) 5V / 3A (15W) 5V / 3A Raspberry Pi 5 5V / 5A (25W) 5V / 5A (high-power splitter needed)   For Raspberry Pi 3 and 4, a PoE splitter with a 5V/3A output is recommended. For Raspberry Pi 5, a high-power splitter with 5V/5A output is required. 2. PoE Standard Compatibility PoE splitters must comply with the correct IEEE 802.3 standard to deliver enough power: --- IEEE 802.3af (PoE): 15.4W – Sufficient for Raspberry Pi 3 but not ideal for Pi 4/5. --- IEEE 802.3at (PoE+): 30W – Recommended for Raspberry Pi 4 (5V/3A). --- IEEE 802.3bt (PoE++): 60W-100W – Required for Raspberry Pi 5 (5V/5A). For Raspberry Pi 4, choose a PoE+ (802.3at) splitter. For Raspberry Pi 5, use a PoE++ (802.3bt) splitter. 3. Voltage Output --- Raspberry Pi boards use a 5V power input via USB-C (or Micro-USB for older models). --- A PoE splitter should output exactly 5V to avoid damage or instability. --- Choose a PoE splitter with a fixed 5V DC output. 4. Power Connector Type --- Raspberry Pi 4 and 5 use USB-C for power. --- Raspberry Pi 3B/3B+ uses Micro-USB. --- Some PoE splitters come with DC barrel jacks instead of USB connectors. In this case, a DC-to-USB adapter is needed. Choose a splitter with a built-in USB-C or Micro-USB connector for easier setup.     Recommended PoE Splitters for Raspberry Pi 1. For Raspberry Pi 3B / 3B+ TP-Link TL-POE10R PoE Splitter --- IEEE 802.3af (15.4W) compliant --- Adjustable output: 5V/9V/12V --- Micro-USB adapter included 2. For Raspberry Pi 4B (2GB/4GB/8GB) iCreatin Active PoE Splitter (5V/3A USB-C) --- IEEE 802.3at (PoE+) compliant --- Output: 5V/3A via USB-C --- Ideal for stable Raspberry Pi 4 operation 3. For Raspberry Pi 5 UCTRONICS PoE++ Splitter (5V/5A USB-C) --- IEEE 802.3bt (PoE++) compliant --- Output: 5V/5A via USB-C --- Supports high-power Raspberry Pi 5 setups     Alternative Solution: Official Raspberry Pi PoE HAT For Raspberry Pi 3B+ or 4, you can use the Official Raspberry Pi PoE+ HAT, which integrates PoE functionality directly onto the board. --- Simplifies wiring – No need for an external splitter. --- Supports PoE+ (802.3at) for 5V/2.5A output. Not compatible with Raspberry Pi 5 (as it has no PoE pins).     Conclusion: Best PoE Splitter for Your Raspberry Pi --- For Raspberry Pi 3B/3B+ → TP-Link TL-POE10R (5V/2.5A Micro-USB) --- For Raspberry Pi 4 → iCreatin PoE Splitter (5V/3A USB-C) --- For Raspberry Pi 5 → UCTRONICS PoE++ Splitter (5V/5A USB-C)
