DSLRKIT Power Over Ethernet PoE HAT IEEE802.3af DC 5V 2.5A with 1.5KV Isolation for Raspberry Pi 4B 3B+ 3B Plus

The media could not be loaded. This POE hat is wonderfully compact. Most other Pi POE hats cover the entire pi, but this leaves the majority of the board open. This is ideal if you plan on using a short passive cooler for the cpu or just want your pi POE-powered but passively cooled.The hat is slightly taller than other POE hats, and so this should be taken into account depending on how you plan to install it. (I use a 3d printed 1u rack for my Pis, and with this hat it's a struggle to fit)Compatibility is perfect, working fine with both the Raspberry Pi 3b+ and 4b.Included are two standoffs, two screws and two nuts. Though I wouldn't say these are 100% necessary, they are nice to have to add extra support to the hat when installed.Overall this is a wonderful POE Hat for the price, and honestly can't be faulted.

Make sure your pi has the separate 4 pin power inputs required for this poe hat. They can be located just behind the network socket and are standalone from the main GPIO pins. No problems with this, other than it will not fit inside the standard pi cases that are available, I luckily can print my own (rackmounted) using the 3d printer I have

The POE from my network switch is now happily driving my pi 3B+ but it is just a shame that it is not compatible with the standard pi case without modification as the PCB has been left unnecessarily larger than the opening in the top of the case. Carving off one of the large lugs on the lid lets the top be clipped in place, and therefore the sides be fitted but the top is still pressing on the PCB and so keeping the case from shutting completely. The fact that I could get it to work, sort of, prevents me knocking off another star.You can't fit the supplied standoffs as they uses the holes used by the bottom of the standard case. The connector is so tight that this is not a problem.This pi had run passively cooled with no heatsink for a couple of years but now seems to be getting warmer. The voltage measures 5.07V so not a concern there. Perhaps just a lack of convection makes the difference? I think a heatsink is definitely in order now to be sure. A tall one can still be fitted as long as it is no larger than the processor.Freeing up a power socket was the main reason for getting this and it has done that.Update: Admittedly it took a few years but the PoE hat has now failed in that the Pi now crashes every day or so. If I plug into a USB power supply it is solid even with the PoE hat attached. No visible cap failures but that is not conclusive.

Bought 10 of these for my rack of raspberry pi servers, great to not have to have all the extra power leads now.

Used this for a while now, seems reliable. Powers a Pi 4 used as a NAS and DNS server with ad filtering without issue. Would recommend

Did not work on pi 4 model b, correct injector voltage but the hat got incredibly hot, hot enough to very slightly scald my skin.

It is well made and works as expected. The only issues I have with it is that I don't think I can add any active cooling options to my Pi 4B now that I've added the POE hat.As other have said getting a case is also a problem because of the extra height the hat adds to the Pi 4.

The device appears to work. I cannot say if the claims for EMC compliance (CE mark, FCC logo etc) are genuine or not. Connector pins were bent (so had to be straightened) on both of the devices which I bought and the insulating sleeve of one electrolytic capacitor (at the edge of the board) was scratched, as if it had been piled with and jarred against others. The conclusion is that there was rough treatment in production. (This damage could not have occurred during transport to me, since each device was contained in a separate cardboard box and both boxes were undamaged). As others have reported, the 40-way connector appears to be hand-soldered on top of the board and this in such a way that solder has run some way up the pins. In summary, this is another device made "à la Chinoise". I bought two for evaluation for possible inclusion in a PoE product, but have decided that there are better options.

Fonctionne bien depuis plusieurs mois !Pas de chauffe excessive même sans ventilateur.Très bon rapport qualité prix

Macht genau was es soll, hab die Erweiterung jetzt knapp drei Wochen im Einsatz und möchte sie nicht mehr missen.

L'HAT PoE in questione è molto economico, tanto quanto brutto, ma fa il suo lavoro egregiamente.Attualmente il Raspberry pi 4 4GB a cui è collegato ha 3 mesi di uptime senza alcun problema.Il raspberry è collegato via PoE ad uno switch Unifi 16 PoE Lite, il quale riporta un utilizzo di 4W circa (protocollo PoE+).Personalmente non ho avuto problemi di surriscaldamento nonostante il Pi sia dentro ad un Rack da 10" senza ventilazione, con una temperatura media interna di 40°C.Unica pecca è l'ingombro che questo HAT occupa sopra al Pi. È molto difficile trovare un case che lo racchiuda e pertanto io al momento lo sto tenendo in un case per Raspberry ma ho tolto la copertura superiore.Ad ogni modo, se dovete mettere un Raspberry in un rack ed avete poco spazio (e poche prese) a disposizione, lo straconsiglio vivamente. Tra l'altro costa meno che procurarsi un alimentatore da presa di corrente compatibile col Pi, ovviamente ammesso che abbiate un power injector (che anche nel caso non so se sia compatibile) o uno switch PoE intelligente.

Worked fine for a month or so then it just stopped working.

Fits ok. But had to extend standard cluster case. Most valuable missing noise from fans. Allows heatsinks on raspberry.
