The Raspberry Pi has sold millions of copies worldwide since its first release in early 2012 and is still very popular. Because many Raspberry Pi users do not only have a single-board computer at home, but also 4-5 pieces.
One functions as a HD media player with external hard disk for the home cinema or as an Internet radio with display, the next as a webcam server for camera surveillance with live stream to the mobile phone, then another for home automation such as heating or lighting control and another as a simple WLAN printer server or as a mini-computer for general surfing on the Internet, to name just a few application scenarios.
You will notice that the little ''jack-of-all-trades'' can not only do a lot, but is also extremely cheap and that is what makes it so attractive. The only thing you should bring along is a flair for programming and not even that, because you can also simply reprogram according to the instructions in forums or books, or you can easily install a finished image on the Raspberry Pi - have the courage to do so!

New Raspberry Pi 4 B
- 1.5 GHz ARM Cortex-A72 Quad-Core CPU
- 1GB, 2GB or 4GB LPDDR4 SDRAM
- Gigabit LAN RJ45 (up to 1000 Mbit)
- Bluetooth 5.0
- 2x USB 2.0 / 2x USB 3.0
- 2x microHDMI (1x 4k @60fps or 2x 4k @30fps)
- 5V/3A @ USB Type- C
There are the following 3 different variants
- Raspberry Pi 4 B 2GB with 2 GB memory (ArtNr.: RASP PI 4 B 2GB)
- Raspberry Pi 4 B 4GB with 4 GB memory (ArtNr.: RASP PI 4 B 4GB)
- Raspberry Pi 4 B 8GB with 8 GB memory (ArtNr.: RASP PI 4 B 8GB)
Due to the other connections, like 2x microHDMI instead of 1x HDMI as well as USB Type-C instead of microUSB, but also due to the exchange of LAN port and USB port, new housings are necessary. Otherwise the existing accessories are fully compatible with the new Raspberry Pi.
Clues:
- for full functionality you need the latest software, to be found at www.raspberrypi.org or in our online shop
- it is recommended to use the original or equivalent power supply (without e-market cable) to avoid possible problems with the USB-C connection.
- we recommend to use the Raspberry Pi with a heat sink to avoid possible overheating. We also recommend to use the Raspberry Pi in a closed housing only with sufficient cooling or ventilation.
- please connect the screen to HMDI 0 (next to power supply) and then start the Raspberry Pi. Use HDMI 1 only with 2 monitors!
