## Description

Descripition:The Power-over-Ethernet (POE) hat offers a convenient and cost-effective way to deliver power to your device. It delivers clean and reliable power to PI 3B+ and Pi 4.Warning:1. PoE power output must be within the budget of the switch when powering multiple boards!!! STANDARDS COMPLIANT POWER OVER ETHERNET SWITCH REQUIRED!!!2. The network switch or power sourcing equipment (PSE) must be compliant with the IEEE 802.3af or 802.3at PoE standard, particularly section 33.4.1 with regards to PSE electrical isolation of the leads.3. "Passive PoE" (DC 24V or 48V) is not standards compliant and may cause damage to equipment.4.Do not use this product in an enclosed case without active air circulation!!Features:Easy to assembleCompatible With Raspberry Pi 4B / Raspberry Pi 3B+Built-in Cooling FanSupport IEEE 802.3af or 802.3at PoE standardSpecifications:Input: IEEE 802.3af Compliant PoEOutput: 5V +-5% [up to 2.5A]Protection Circuitry: Transient Overvoltage, Undervoltage Lockout, Thermal Shutdown, Foldback Current LimitingActive airflow and adequate cooling required for stable continuous operation at high load.Weight: 30gPackage Including1 * Power-Over-Ethernet (PoE) Hat with 3007 Cooling Fan3 * M2.5*9+6 Copper Stick3 * M2.5 Screws3 * M2.5 Nuts1 * Aluminum Heat Sink1 * Screw Driver

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great
  

*by J***E on Reviewed in the United Kingdom on 25 September 2020*

Works perfectly with my Pi4. Makes sense to use one of these if you have a POE switch. Installation was straightforward and it should fit in a standard case.

### ⭐⭐⭐⭐⭐ 







  
  
    Brilliant, cheaper and better than official PI HAT POE
  

*by L***N on Reviewed in the United Kingdom on 15 June 2020*

Much preferred to the official Pi POE HATBigger fan, cooler temperatures and cheaper

### ⭐ 







  
  
    Damages Pi 4 if you use provided mounting hardware.
  

*by M***R on Reviewed in the United Kingdom on 11 November 2020*

Mounting the device to the Pi with the provided standoffs and screws causes a short. It fried my Pi4 and broke the POE hat.
