  • RASPBERRY PI 4 的终极力量 ETHERNET 帽:为*新的 Pi 4 提供干净可靠的动力! 与多个电源适配器相比,以太网供电既简单、节能又经济实惠。 为多个板供电时,PoE 功率输出必须在开关的预算范围内。 PoE 开关和树莓 Pi 4 型号 B 单独出售。
  • 符合标准标准的以太网开关电源要求:网络开关或电源设备(PSE)必须符合IEEE 802.3af 或 802.3at PoE标准,特别是关于PSE的电隔离的*33.4.1节。 "被动式 PoE"(DC 24V 或 48V)不符合标准,可能导致设备损坏。 一些 Ubiquiti 开关不提供适当的隔离,因此请使用专业版本!
  • 专为群集节点构建:简化电缆管理,并使用 POE 扩展本地云! 通过单个 POE 开关为五、十、二十个 Raspberry Pi 4 型号 B 板供电。 这款 PoE 帽子设计超越了官方Raspberry Pi PoE HAT 和市场上其他产品所设定的电源传输标准。
  • 强烈推荐:请勿将本产品放在封闭式盒子中使用。 帽子周围的 Raspberry Pi 4 B 型气流必须足够,以确保性能和稳定运行。
  • 兼容:支持Raspberry Pi 4 以及Raspberry Pi 3 型号 B+。

5.0 颗星,最多 5 颗星 These are THE BEST PoE hats for the RaspberryPi 4b
2020年2月18日 在美国审核
I've purchased just about every PoE hat available for the RP4b from multiple manufacturers, and these from LoveRPi are by far the best I've come across. I now own 5 of them (4 "Compact" in the cluster in the photo, and 1 "Professional" not pictured).

I've had no issues at all with poor grounding, or powering peripherals, etc. from these LoveRPi PoE hats. They've supplied steady, reliable power to all the various devices and setups I've tried. I have powered external SSDs over USB with them (even plugging in and unplugging while powered to see if the power would surge/spike). They survived all my tests like the champs I now trust them to be.

I have no hesitation about recommending these PoE hats for any project that demands a PoE setup.

***Further information for those who want to replicate a known working setup***

Powering my RP4b cluster is the Netgear GC108PP semi-managed switch: https://amzn.to/2HzEbnf (referral link). I chose this switch because the management interface tells you the power and data being consumed by each port. The "subscription" for cloud management is optional and opt-in (this is good), and I personally subscribe since it is able to tell me whenever my internet service provider has an outage - It will notify me of a "site down" alert to my phone (through their app), and via email. If an individual device goes offline, you can set alerts for that too. The subscription is also about $10/year, so not bad at all. Without the subscription, everything still works, and you can do all the management through the Netgear "Insight" app, or from the web interface.

The "case" you see is the iUniker RP4 cluster case found here: https://amzn.to/2Hyjfgg (referral link). The COMPACT PoE hats will work with this cluster case, but there is zero clearance between the side of the fan and that square part that sticks up off the PoE hat. You just have to install each layer very carefully. The "Professional" version of this PoE hat WILL NOT work with this case. I've been very happy with the combination of my LoveRPi Compact PoE hats, and this case - The temperatures on my RPs never get above 45C with this setup, and thus I never experience thermal throttling despite the heavy compilation loads they are sometimes (frequently) under.

The NAS is 11 years old, and is the primary data store for each of my RP devices. This particular one is no longer sold nor supported, but I'm thinking of upgrading to a Synology or QNAP one of these days. The Synology devices are cheaper, but QNAP are more powerful. As I haven't personally used either yet, I can't recommend one versus the other (and I also refuse to do referral links for untested setups).

Good luck with your projects everyone! If you read this far, I hope you found this review helpful. If so, please hit that "Helpful" button Amazon provides so I get the notification! Thanks!

Works great! Takes up very little room. The only issue is that it covers the SDRAM chip so you cannot put a heatsink on the RAM. Otherwise it works perfect with no issues on all of my Pi 4’s.

5.0 颗星,最多 5 颗星 Fits CanaKit Case with fan
2020年2月22日 在美国审核
I can't speak to durability because I just installed it but it is working great. I believe this model (Pro) has the best design when compared to all current makes and models that have isolation. As far as I can tell, this is the only model that will fit in the standard CanaKit case with the fan installed (see pic). I did have to remove the heatsink from the SDRAM.

Most brands claim active cooling (fan) is needed. PoE hats typically use the power pins that are needed for a fan. Unlike other brands, this board has extra power pins so you can easily reconnect your fan after installing it.

5.0 颗星,最多 5 颗星 Easy as Pi!
2019年12月6日 在美国审核
Despite being for the ‘Rospberry Pi’ as described on the box, it works great for the Raspberry Pi 4b.

It drops right on top of the GPIO pins and wraps around the main CPU heat sink. I had to remove the heat sink on top of the RAM, but the LAN and CPU heatsinks could remain. Overall, it seems stable. I have it plugged into a UniFi PoE Switch. So far so good. Very pleased to be able to eliminate another cord. It fits perfectly in the CanaKit supplied case as well. Just drop it in and plug in the LAN cable. Simple! Thanks!
