RaspberryPi is cheap and can do lots of things including WALLBOARDS.
Here in my company we used Chromecast, but had the disvantage of the need to use a device to stream the dashboards to it.
So I got a brand new Raspberry Pi 3 - even Klipfolio's FAQ saying that was uncompatible due to minimal requirements - and put to test.
The result? IT WORKS FANTASTIC!
Didn't have to do much, just installed the UBUNTU MATE, which I think its a stable and lean version to run o Pi (Raspbian's also a good choice, but I preffer Ubuntu), and ran some settings to fit to my needs:
Autostart hiding mouse;
Autostart opening CHROMIUM* (and I set my default homepage to a public link of my dashboard) -> used a parameter to start in KIOSK mode, this way always start in full screen mode;
You don't have to set your default homepage to your dashboard, while you're setting the chromium to start with GUI you just have to put
chromium-browser --kiosk http://yoururl.com
*Important: I tried to use FIREFOX, but FF just can't run Klipfolio Scripts (JQuery).
Set a static IP address - this way I can control everything on my RPi remotely using ssh or VNC;
And my Dashboards now looks AMAZING!
Low cost solution, highly customizable and I don't need a dedicated or shared device to stream my dashboards.
Does anyone tried to use a RPi already?
