Raspberry Pi 4B


Raspberry Pi 4B is a tiny desktop computer that significantly helps with various projects in robotics, multimedia, networked AI core, and much more. You can connect several Original Prusa MK2.5/S or MK3/s/+ printers to one Raspberry Pi 4B to add PrusaLink functionality to them and to connect them to Prusa Connect. Additionally, you can attach one or more cameras for printer monitoring—be it an RPi camera connected via CSI or a USB webcam. Other than connecting the Original Prusa printers, the Raspberry Pi 4B can work as a cheap and simple desktop computer that comes with 2GB or 4GB RAM, (depending on the variant) onboard wireless network connectivity, Bluetooth 5.0, Gigabit Ethernet, and USB 3.0. The board supports two 4K displays and various add-ons.


The whole installation process of Prusalink / Prusa Connect for your MK2.5/S or MK3/S/+ with Raspberry Pi 4B is thoroughly explained at our knowledge baseAfter the successful setup of PrusaLink / Prusa Connect, you may install a camera according to this guide.
