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!
