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 have not only a single board computer at home, but partly 4-5 pieces.
One functions as an HD media player with an external hard drive for the home cinema or as an Internet radio with display, the next as a webcam server for camera surveillance with livestream to the mobile phone, then one 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 a few application scenarios.
You will notice that the little "jack-of-all-trades" is not only capable of a lot, but is also extremely inexpensive, which is what makes it so attractive. Only the inclination to programming you should bring along and not even that, because you can also simply reprogram according to instructions from forums or books, or install quite comfortably a finished image on the Raspberry Pi - dare!

- 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) H.265/H.264

There are the following 3 different variants -
- Raspberry Pi 4 B 2GB with 2 GB RAM
- Raspberry Pi 4 B 4GB with 4 GB RAM
- Raspberry Pi 4 B 8GB with 8 GB RAM
Important note Due to the other connections, such as 2x microHDMI instead of 1x HDMI and USB Type-C instead of microUSB, but also due to the exchange of LAN port and USB port, new housings are necessary (see accessories). The board now also requires a power supply with a USB type C connector with at least 5V/3A (see accessories) and no longer a microUSB power supply with 5V/2.5A. Otherwise, the existing accessories are fully compatible with the new Raspberry Pi.
Hints: - For full functionality you need the latest software, available at www.raspberrypi.org or in our online shop.
- it is recommended to use the original or an equivalent power supply to avoid possible problems with the USB-C port.
