Raspberry Pi Setup, Tips and Tricks

Hardware Setup

• We have one Raspberry Pi for each Screen on the Wall
• They are attached to the backside of the wall (small black boxes)
• Each of them is connected to an HDMI switch that switches between the PasPi output and the input from the "Datapath X4 Module"
• The HDMI splitter only works when powered by the HDMI port of it's RasPi - so the RasPis need to have power even if you want to use input from the Datapath!
