Bill Of Materials / Hardware Assumptions

This is a surprisingly straight forward project that has minimal in the way of hardware requirements. Below you'll find a list of everything we recommend / assume.

  • Raspberry Pi 4 with at least 2Gb of RAM
    • An equivalent board with at least 2Gb of RAM capable of running Ubuntu 64bit Linux can be used instead but we do not support anything but the Raspberry Pi 4 at this time
    • Please note: RAM usage is significantly affected by source image resolution /and/ panel size. 2Gb of RAM should be enough for a 2k screen and 20Mpx source images. If you're not sure get a 4Gb Raspberry Pi.
  • HDMI Monitor
    • This 5.5" 1440x2560 (2k) display looks promising and is being tested currently
  • Geekworm Armor Case
    • If you would like an always on fan, select the model with the integrated fan option
  • Pimoroni Fan SHIM
    • This has better cooling as well as on/off support
    • You probably want this instead of the Geekworm armor case with fans
    • This will NOT require soldering to use but assumes you have room to slip the fan all the way down on the main header
  • USB to Serial adapter
    • There are a lot of options, choose one you know that will work well
  • Mini HDMI to HDMI adapter
  • HDMI cable
  • USB disk (thumb drive / ssd) for storing pictures
    • This is optional but will help prevent micro sd card wear if regularly changing photos or running backups
    • The Sandisk Ultra Fit USB disks are great options and work well with the Raspberry Pi boards
  • 1x micro sd card
    • Must be at least 16Gb. The base install of software consumes almost 8Gb of storage, you'll want more than 8Gb to properly buffer updates and upgrades
  • Power supply (at least 3A to avoid voltage issues)
