Great product

Reviewed in Australia on 18 December 2019

This is what you would expect when you buy a Pi. Its a mini Linux computer! Being the Pi 4 model B with 4GB RAM it is way faster then the older ones or even the ones with less RAM. I can only compare it to my friends gen 1 Pi which is wayyy slower then mine to the point he is now considering upgrading to the Pi 4. It will run fairly hot (70 degrees celcius+ when at full load) so I recommend buying a case with cooling. Also remember to buy a micro hdmi cable, micro SD card and power supply, unless you're buying a kit which would come with that.

Good performance from a tiny little computer

Reviewed in Australia on 27 April 2020

I use my Pi to run a Octoprint server for my Ender 3 Pro. It does feel like overkill for this use case but I do get the peace of mind knowing that the performance of the Pi is not going to affect my 3D printing in any negative way. I may eventually decide to repurpose this Raspberry Pi 4 model B for something more deserving of it's performance (I was thinking of using it as the heart of a file server but I have to find someway to attach multiple SATA harddrives to it) and replace it with a earlier model but until then, the Pi 4 will soldier on as my Octoprint server.

Though, you must be sure you're USB power cable is a smart cable that can allow enough amps if the power source is a PD charger, since a PD charger won't give enough amps unless the cable says it's ok to.

Fantastico!

Reviewed in Italy on 22 September 2019

Uso Raspberry Pi da quando è uscito sette anni fa, passando per tutti i vari modelli: finalmente, dopo un'attesa di tre mesi, ho messo le mani anche sulla versione da 4 GB. Fantastica (come sempre, del resto...)

(Se già conoscete RPi, saltate questa prima parte)
Questo piccolo computer ha i suoi punti di forza nel consumo ridotto, nel costo e soprattutto nell'immensa comunità di supporto. Può essere utilizzato come computer generico o per ospitare servizi casalinghi che devono sempre rimanere accesi (da torrent a server multimediale); offre il meglio di sé quando vi interessa interfacciarvi con l'hardware auto-costruito.
Nel pacco troverete solo la scheda; per renderlo operativo occorre:
* una microSD, almeno 8 GB se volete l'interfaccia grafica; deve inoltre essere veloce se volete spremere al massimo RPi
* un alimentatore USB-C, da 2-3 A.
* un cavo micro HDMI, un mouse ed una tastiera. Indispensabile per chi comincia, ma opzionale per molti usi
* Utile, ma non strettamente necessario, un dissipatore/ventolina, soprattutto se lo userete dentro un case.
Potete collegarci ben due monitor HDMI, anche 4k. Come sistema operativo ho praticamente sempre usato solo Rasbian (free), ma ne esistono anche altri, ed altri ancora seguiranno.

(per chi usa già RPi)
Questa versione 4 è il potenziamento della precedente anche se stavolta alcuni aspetti sono a mio parere un miglioramento sostanziale. Cosa è cambiato:
* La rivoluzione è (finalmente!) l’incremento della RAM. Questo da 4 GB è il top. Dipende da cosa lo usate per fare, ma in alcuni casi era davvero necessaria
* La rete ora è davvero da 1 Gbit/s; la versione precedente lo era solo sulla carta e non andava oltre i 300 Mbit/s, ora arriva a 950 Mbit/s (testata con iperf)
* Arriva USB3, cosa che permette di usare decentemente un SSD “esterno”.
* L'aumento di prestazioni del processore è significativo, non tanto per il piccolo aumento del clock, quanto per la diversa architettura. In rete trovate i numeri; all’atto pratico questo da 4GB è davvero usabile come PC, soprattutto se usate una SD particolarmente performante (o montate / su un SSD USB3)
* Possibilità di doppio monitor, anche da 4k (e anche a 60 Hz, se ne usate solo uno). Non penso sfrutterò la cosa, in genere lo uso headless, ma apre possibilità interessanti

Non tutto è oro, ovviamente:
* Qualche rischio di surriscaldamento. Per ora lo sto usando senza alcun problema prevalentemente aperto, senza monitor e senza alcun dissipatore. Situazione un po' diversa se collegate un monitor 4K@60Hz: probabilmente nelle giornate calde vi servirà un dissipatore (ed anche una ventolina, se lo chiuderete in un case)
* Serve un alimentatore di qualità (assorbe qualcosa più di 1 A a pieno carico e senza nulla di collegato, quindi meglio stare sui 2 o 3 A); il connettore USB-C ha praticamente eliminato i problemi di cavo delle precedenti versioni con micro-USB. Per i test di temperatura consiglio "cpuburn" (da cercare in rete)
* Purtroppo il PoE continua ad essere una costosa opzione (peccato: sarebbe stato davvero utile!) Io ho preso questo
* Per chi già aveva una vecchia versione del Raspberry, serve qualche adattamento: cavo micro HDMI, alimentatore USB-C, incompatibilità con i vecchi case… Per la micro-SD, serve ovviamente la versione aggiornata di Buster (Raspbian 10); è invece incompatibile con tutte le precedenti versioni di Raspbian, con Windows 10 core e con molti altri OS (che non sto usando).

Come funziona:
* Perfetto per ospitare servizi, anche pesanti. Ho fatto un test con con un server web e database piuttosto pesanti su SSD USB-3 e direi assolutamente usabile! In questo il miglioramento di rete, RAM, USB e processore rispetto al 3B+ fanno davvero la differenza
* Buono come PC “normale”. Nulla di paragonabile ad un i7 o un Ryzen, ovviamente, ma le prestazioni sono migliori di quelle di molti PC entry-level (ma ad un costo ben diverso…).

Che dire: sta-consigliato! I difetti ovviamente ci sono, ma la RAM in più mette tutto il resto in secondo piano.

Il prezzo delle varie versioni ora è allineato a quello ufficiale e quindi la scelta dipende solo dalle vostre esigenze. Per evitare fregature vi metto i prezzi "giusti":
* La versione da 1 GB a 40-45 euro incluse tasse e spedizione, per la sola scheda (non un "kit")
* La versione da 2 GB a 50-55 euro
* Questa versione da 4 GB a circa 65 euro
* Purtroppo le versioni precedenti, più che sufficienti per una miriade di usi, ora sono fuori produzione ed hanno quindi assunto prezzi "da antiquariato" e non vale più la pena acquistarle (a meno di super-offerte sotto i 30 euro)

Schönes Teil.... ein echter Fortschritt

Reviewed in Germany on 25 August 2019

Gut verarbeitet und schneller. Der RAM ist endlich auch kein Flaschenhals mehr. Habe ihn mit einem vernünftigen Kühler auf 2 Ghz CPU mit 600 Mhz GPU stabil laufen. Leider ist die Software im allgemeinen noch nicht so weit oder Beta. Aber das kommt noch. Habe meinen 3B+ in Rente geschickt...

Hier mal eine kleine Anleitung:
1. Die beiden Lüfter des Kühlkörpers durch kleine Unterlegscheiben an den acht Schrauben um 1 mm anheben. Der Luftstrom verbessert sich merklich.
2. Die vier Schrauben, die Ober- und Unterseite des Kühlers zusammenhalten, reichlich mit Wärmeleitpaste einschmieren und erst dann reindrehen. Besserer Wärmeaustausch zwischen den beiden Kühlerhälften.
3. Zwei 4 mm dicke Wärmeleitpads zwischen die Platine und der unteren Kühlerhälfte, und zwar da, wo auf der Oberseite die CPU und die Spannungsregelung sitzt. So ist die Kühlerunterseite wärmetechnisch voll eingebunden, da sie sonst keinen Kontakt zum Raspi 4 hat, außer mit den Montageschrauben.
4. Mit "sudo nano /boot/config.txt" die passenden OC-Einstellungen eintragen.

Ich habe den Raspi 4 bei einer Raumtemeratur von 27 Grad (der letzter Sonnabend war wirklich sommerlich) stundenlang im Stress gehabt. Mehr als 48 Grad auf der CPU kamen mit dieser Lösung nicht zustande, und das bei 2 GHz. Als Netzteil nutze ich eines von einem Huawei Mediapad M5, liefert 5 Ampere.

Vendeur impeccable malgré un prix un peu élevé mais produit retourné

Reviewed in France on 30 August 2019

Verified Purchase

Comme le dit le titre le vendeur malgré un prix un peu élevé a très bien envoyé et emballé le produit . le commentaire n'est pas la pour le dénigrer.
J'ai par contre renvoyé ce Raspberry 4 pour plusieurs problèmes. le premier ayant entraîné le reste:
J'ai effectué les démarches de mise en route de ce Raspberry 4 comme les précédents et en suivant les instructions compris sur leurs sites, mais impossible de le mettre en route l'écran reste figé sur l'écran arc en ciel sans possibilité de débloquer la situation malgré les patchs proposés par le site officiel.
A la recherche de solutions c'est a cet instant que je suis tombé sur tous les problèmes concernant ce nouveau modèle:
- Certains câbles usb-c sont incompatibles avec le port usb-c au point que la firme va proposer une nouvelle version du pi 4 .
- Problème de surchauffe ! Réel dans mon cas même si celui-ci est resté fixe sur le "rainbow screen" il chauffait anormalement.
- Des patchs plus ou moins clairs pour palier à un problème de recovery à peine 2 mois après la sortie.
- Et surtout impossible de le mettre en route, il aurait été cool de nous mettre à disposition un tutoriel spécifique à ce nouveau modèle, cela aurait pu m'aider a s'avoir si le problème venait de moi ou de mon Raspberry .

Alors problème d'alimentation , ou problème avec ce modèle, ou cette commande ? je ne sais pas, ne préférant pas porter un jugement hâtif j'ai donc renvoyé le produit.

En clair le vendeur n'est en rien responsable de tout cela , je mets 1 étoile car je ne juge que le produit , je partage toujours mes avis à la communauté et je trouve que cette nouvelle version mérite quelques ajustements je vous conseille donc d'attendre un peu que les défauts soient corrigés pour vous plonger dessus.

Epic - but needs thoughtful cooling

Reviewed in the United Kingdom on 28 September 2019

Verified Purchase

Purchased a pair of Pi 4s to run a domestic network service set (mainly DNS and DHCP, taking over from my router). using the Pi 4 and a copy of PiHole (caching DNS / sink) it is possible to block advertising from your entire home network (including PC, TV, tablets, smartphones, etc. Fabulously easy to set up for the task.

Positives
1. Remarkably powerful computer-on a board for a competitive price
2. Compact and unobtrusive (different layout means you will need a Pi4-specific case, but plenty available)
3. Addition of Gigabit Ethernet makes a huge difference in network performance
4. Two USB-3 ports means super-fast storage easily added with connected SSD
5. Vast library of projects, software, robotics and addons remain compatible and fun to experiment with
5. Dual 4K monitor capability via pair of microHDMI ports brings serious Home Theatre potential

Negatives
1. Runs much hotter than earlier models and will throttle when it gets warm. No cooling provided - it really needed to have shipped with (optional) heatsinks
2. Prices starting to creep up for more powerful models - by the time you add micro-SD, case, etc, it can get expensive

Sum-Up
The Pi remains one of the most popular hobbyist, single-board computers for a good reason. Powerful, flexible, reasonably easy to set up and use and with lots of available support, are lots of fun, too. You do need good cooling with this one, though.

Das Teil wird immer Besser

Reviewed in Germany on 12 October 2019

Verified Purchase

Der Raspberry Pi 4 ist nicht mein erster Pi, ich besitze auch einen 3er und einen 3+ und ich muss sagen, das Teil wird immer besser.

Der Neue Pi 4 kommt mit echtem Gbit und echtem USB 3.0 an.

Durch die Neuen, schnelleren Anschlüsse hat der Pi nun auch endlich die Möglichkeit, Transferraten intensive Arbeiten in relativ kurzer Zeit zu verrichten.

Die Anschlüsse des Pi 4:
1x Gbit Ethernet (echtes Gbit)
2x USB 3.0
2x USB 2.0
1x DSI Anschluss für Raspi 7" Touchscreen
1x Raspi Kamera Anschluss
2x Mini HDMI
1x 3,5mm Klinke
und 1x Typ-C zur Spannungsversorgung

achja und natürlich die GPIO leiste die man von den Vorgängern kennt ist auch noch mit auf dem Board.

Natürlich hat der Pi 4 auch einen Stärkeren Prozessor mit an Board, dadurch ist jedoch auch die Wärmeentwicklung im vergleich zum 3er gestiegen. Dies sollte man bedenken, um evtl einen Kühlkörper gleich mit zu bestellen, in den meisten Gehäusen liegen diese schon bei.

Was sehr schön ist, den Pi 4 gibt es endlich mit mehr RAM 1,2 oder 4 GB, das einzige ist hier dann der Preisunterschied

Ich bin sehr begeistert was dieser kleine Kerl alles kann und möchte ihn und seine Geschwister nicht mehr missen.

Zusammenfassung:
+ Echtes Gbit Ethernet
+ USB 3
+ Typ-C Buchse für Spannungsversorgung
+ Wahlweise bis zu 4 GB RAM
o Teils hohe Wärmeentwicklung, je nach Anwendung
--------------------------------------------------------------
+ Positiv
o Neutral
- Negativ
