Note the new dual micro HDMI connectors (up to 4kp60 supported), 2 USB 3.0 connectors and full gigabit network connector now. It is available with 1, 2, or 4 GB of LPDDR4-2400 SDRAM.
This is a game changer for energy efficient computing. I costs less than a zero client while locally being fast enough to serve as a desktop computer for most used applications. In an educational computer lab, all you now need is a file server for students to save their files, submit homework to teacher, and receive comments on their homework. In the future it would be interesting to set up PXE booting so that all updates could be done from a central file server.
Mine uses 3.6-4.1 watts idling at the Desktop with one 1920×1080 monitor, Logitech unifying wireless keyboard/mouse receiver, and headphones attached. Playing a Youtube video raises power usage to 4.3-5.6 watts.
Released at the same time is the new Raspbian based on Debian 10, buster. Assuming that you install Raspbian – buster and LibreELEC you will find that in Raspbian, VLC is missing the codex for viewing commercial DVD movies. You will want to execute the following two commands in the terminal (where I have not shown their output):
pi@raspberrypi:~ $ sudo apt update
. . .
pi@raspberrypi:~ $ sudo apt install libdvd-pkg libdvdnav4
. . .
In LibreELEC, the default audio goes through the HDMI output, so if this is connected to a monitor or TV display that doesn’t support HDMI audio, you will need to connect your headphones or amplified speakers to the audio connector of the PI 4B and configure the audio in Kodi media player to be analog.
I am looking forward to setting up X2GO client which will now have full gigabit network support for running remote computer desktop sessions when more computing power is required than the Pi 4B can provide locally.
Note that Raspbian – buster no longer supports the “framebuffer_depth=16” option in /boot/config.txt, so I do not currently have a way to add displaylink DL-125 or DL-165 USB adapters to the Pi4B for more than the 2 HDMI built in display outputs of the Pi 4B. Need to research whether this is a firmware limitation on the Pi 4B or whether would work with the older Raspbian-stretch version. Does anyone have a newer Displaylink adapter supporting 32 bit frame buffer?
