A good option for a RPi. ItGreat product for someone that wants to use Linux but doesn’t want to dedicate another computer. The raspberry pi 8gb is plenty of RAM for a computer like this, and the improvements with the pi 4 over the 3 make it more usable as a desktop computer.I recommend either the official power supply or a good quality usb-c power supply. The official one which I am using outputs 3w and works fine.This will boot to a usb drive, but it needs a firmware update. If you want to do this, look at element14’s site for details.A raspberry pi can be used to tinker with linux, but I personally use them for a Pihole DNS server to block out sites that we don’t want for the kids. Retropie is another use for these devices, and that’s a fantastic one where I dedicate one of these devices. Since it can run Linux, you can find lots of applications. Ive used it for a radio, for gaming, and for a network file share. And I’m doing some geeky stuff, but it’s really easy. Since the microSD cards are inexpensive now, you can swap OSes back and forth or easily replace it if you goof up with little fear.So that is what it’s for, and here is what it is. It’s a small green circuit board that you hook up to power, keyboard and mouse, and a microHDMI (check for an adaptor or cable, as you may not have these around your house. You’ll need an OS on a microSD card, and I recommend downloading NOOBS and writing it to a 32GB microSD.Overall, I have been impressed with my Raspberry pi 4, and this 8GB is way more enough RAM than I need (now I just need more time to tinker). It’s as easy as pi to assemble most of the cases, especially the stock one, so I have even had my 7 or 8 year old build one so that she could learn. I received mine from seeedstudio, and I’m familiar with them from other kids and computers. I’m quite happy with this product and purchase.There was a review section for touch screen, but this is just a computer board. You generally would want a case, heat sinks (maybe not necessary, but it may help against throttling), keyboard, mouse, microhdmi to hdmi cable, hdmi-compatible screen or tv, microSD card (8 to 32GB) and another computer with Internet and a microSD reader to burn the NOOBS image ( or you could buy one)Great device. Only need 2gb RAM if using for homebridge but cannot complain about extra memory. Fantastic unit.I am a network/system's administrator since the dial-up days.I have built my own PCs since the day of the IBM PC-Compatible ((c) 1988 or so for all you whippersnappers).The last I built was a six-core AMD FX6300, 32GB/2TB/GTX1060ti.I'm a unix guy, for whatever difference that makes. I run linux most places, including these two machines.I almost never turn on the AMD machine anymore, except to keep it up to date. Unless I am running steam servers, I don't much need it; the Raspi 8GB is my daily driver. For the year proceeding, the Raspi 4GB was my daily driver.Attach keyboard, mouse, and some mass storage, and you have a serious little linux desktop that will drive two monitors over hdmi, is silent, takes up the space of a couple decks of cards, and consumes something like 15 watts of power, peak. That AMD box: 750 watts.If you can do without windows on your desktop (as in microsoft), or prefer, as I do, to do without windows as much as possible, then you should seriously investigate the sort of system you can build around these little SoCs. I've got a little in excess of 100$US in my current rig. I use it continuously, and it just keeps on delivering the goods.I just can't speak highly enough about it.I bought this, a power supply, a passive cooling box, a mini keyboard.mouse and a micro HDMI to HDMI adapter, added a 64 GB SD card I had laying aounrd and it worked great!The 64GB card needed a special utility to format in my Windows OS (apparently Raspberry PI bootloaded doesn't support NTFS or other filesystems that handle larger drive sizes with the native format tool, but that's not the PI's fault.)My main purpose for buying it was to setup a streaming device that I could use with my smart TV for services Roku doesn't currently support. After playing around with a few of them, I settled on the native Raspbian full desktop and it works fine (I did set the resolution down from 4K to 1080p because I am getting old and the 4K desktop on a 55" screen across the room was just too tiny for me!)My biggest wish now is to find a way to easily power it back on when I turn it off. I like to actually power things down when not using them, but this means I have to unplug and re-plug the power supply. I see that some power supplies come with a on/off button that works like a small extension cable on the USB power adapter, so will probably get one of those next.Does not have a touch screen. Puts out quite a bit of heat, so added a cooling fan. Perfect now. Want to put all the wife's pictures on it.Fortunately, there are many youtube videos to help with the configuration and use of this device. It was not a great bargain at the price.It took a little bit of finagling, but I was able to compile and install the software to reduce Hubble data on this little wonder board (8 GB version). There's a pip repository setup to host ARM-compiled versions of many needed packages. There were still some struggles getting source compilation of Fortran code working (yuck!), but it's ultimately doable. Now it's a nice Jupyter-Lab server for development and data analysis.Hopefully Apple's move to ARM hardware will encourage more software support for the Pi. While the chip supports a native 64-bit bus, the underlying Raspberry Pi OS (in production, as of this review) is still 32-bit. Looking forward to even more power in the future!I didn't want to take a chance with heat, so I bought a case with heat sinks and a fan, and the temperature has remained very reasonable. I also opted for the official power supply (keep an eye on the current ratings of third-party power supplies!) and a fast micro-SD card.Ich habe lange gezögert, jedoch meinem Spieltrieb nachgegeben und mir den Raspberry PI4 mit Allem drum und dran zugelegt. Zuvor hatte ich bereits den Pi in der ersten Version und bin dahingehend kein unbeschriebenes Blatt. Vorweg: Die 8GB-Variante ist absolut unnötig und ich kenne bisher keinen Pi-Besitzer der diese sinnvoll ausgereizt haben soll.Wofür ist der PI geeignet bzw. ausgelegt?- Kleinere Webserver- Netzwerktechnik wie VPN-Gateway, DNS-Server oder auch (kleine) Firewall- IoT-Spielereien (Stichwort: SmartHome)- Steuerungselement in bestimmten Robotik-BastelprojektenAlso PI4 bestellt und gleich geprüft: Taugt der Pi4 mittlerweile vielleicht sogar als Desktop-Ersatz?Die Antwort darauf ist wie erwartend ernüchternd: Ja, Libre-Office funktioniert und auch Mails lassen sich lesen. Aber die Performance ist immer noch ziemlich zäh. Von Youtube oder generelle Videos im Vollbild möchte ich gar nicht erst anfangen. Und ja, ich habe alle Betriebssysteme durch: Von Raspbian, TwisterOS, Ubuntu Mate bis hin zu Windows 10 ARM (s. Screenshot). Ernsthaftes arbeiten ist also nur dann möglich, wenn man sich generell nicht stresst und sich regelmäßig einen Cafe holen gehen möchte ;-)Aber damit hatte ich ja bereits gerechnet. Also zu meinem eigentlichen Anliegen: ThinClient.Der Raspberry Pi4 wäre meines Erachtens der ideale ThinClient (für bspw. VMWare Horizon / Citrix XenDesktop). Firmen wie bspw. ncomputing vermarkten diesen schließlich auch als Solchen. Aber ich sage bewusst "wäre", weil er es nur bedingt ist: Startet man eine Citrix-Session, lassen sich die Anwendungen oder auch Webseiten innerhalb der Session (wie erwartet) zügig öffnen. Kommen da aber bewegte Bilder (wie bspw. Werbungen/gifs) ins Spiel, dann geht die Performance des Pi's schonmal schnell in den Keller. (Das dekodieren des Citrix ica-Traffics scheint den PI doch an seine Grenzen zu bringen.)Von Videos oder gar 3D-Virtualisierung via Citrix oder VMWare mag ich gar nicht erst reden: Youtube im Fenster zeigt sich in der Session noch flüssig, im Fullscreen gibt es jedoch Seitens des Pi's Anzeigeruckler. CAD-Anwendungen im FullScreen ruckeln generell, 3D-Games wie bspw. Overwatch lassen sich über eine leistungsstarke VM mit Nvidia M10 via Citrix HDX-Stream auf dem Pi nur als Diashow darstellen. Wäre ja auch zu schön gewesen. Aber gut: Für normale Office arbeiten ohne Videostreaming ist es Dank MultiMonitoring ausreichend. Für jemanden wie mich, der 3D-Virtualisierung benötigt und auch gerne mal youtubed leider nicht nutzbar.Kurzum: Die Entwicklung des Raspberry PIs geht in die richtige Richtung. Leider ist die Performance trotz des Vierkerners immer noch zu schwach und wirklich nur für kleinere (Spiel-)Projekte zu empfehlen.Wer im IT-Bereich mehr lernen möchte, dem empfehle ich eher eine leistungsstärkere Intel NUC mit einem kleinen i3. Auf dieser können auch mehrere virtuelle Linux-Maschinen zum Lernen angelegt werden (=> Gerade für Spielereien mit Kubernetes & Docker finde ich ein sogenanntes "Pi-Rack" bzw. Pi-Clustering unnötig. Das tun auch VMs).È un gran bel prodotto, attualmente ci ho installato (con moltissima fatica a dirla tutta) archlinux arm a 64 bit.Ma è davvero utile in questa forma? Allo stato attuale consiglio invece la versione a 4gb. Ecco spiegato il perché:Gli attuali sistemi operativi stabili sono solo quelli a 32bit, hanno tutto quello che serve e sono performantissimi. Esiste un os praticamente per ogni uso, quello che ti fa da media (libreELEC ad esempio), quello per il retrogame ( retropie) o quelli general purpose (raspbian)Ma son tutti a 32 bit e sfruttano massimo 4gb di RAM.Per concludere, se avete voglia di sperimentare prendetelo pure, vi avverto che i sistemi operativi a 64bit nn hanno neanche widevine quindi nn potete nemmeno usarlo per guardare Netflix. Ma se magari volete compilare i vostri pacchetti e svilupparci è un ottimo device.Altrimenti andate sul Raspberry pi4 con 4gbSeguendo le logiche del “più grande è meglio” e “più spendo meno spendo” ho preso questa versione da 8Gb.Il prodotto é perfetto, sono totalmente soddisfatto sia di questo che del venditore.Va fatta una precisazione sull’utilità degli 8Gb che onestamente è marginale, per alcune applicazioni particolari che richiedono molta RAM è sicuramente utile ma a livello di fluidità È versatilità nell’utilizzo general porpoise non è sensibilmente meglio della versione da 4gb.Rien à dire de plus c'est du Raspberry quoi. (bon les 8Go sont pas très utiles pour de l’applicatif).Juste vue le prix du bidule sa vous dérangerez de mettre au moins une protection à bulle ou autre chose sur la carte plutôt que de le mettre dans la boite comme sa à ce balader car quand je les reçu il était dans une simple enveloppe donc le boitier en a prix un coup forcement et sur la carte sa va juste un des port usb 3.0 qui était un peu tordu sur le dessus.Si se enciende sin estar conectada físicamente a un monitor encendido: no hay vídeo.Modifico la opiniones anteriores por solución temporalAunque no tenga conectado monitor: Activa la salida HDMI, y muestra resolución 1080p 60HzHay que modificar el archivo /boot/config.txtModificar tres variables: dos se activan con el valor propuesto y otra se activa y se le asigna el valor 76# uncomment if hdmi display is not detected and composite is being output#hdmi_force_hotplug=1hdmi_force_hotplug=1# uncomment to force a specific HDMI mode (this will force VGA)#hdmi_group=1#hdmi_mode=1hdmi_group=1hdmi_mode=76Ahora se puede controlar con VNC® Viewer y tener resolución FullHD
