Breakout is not supported for Raspberry Pi. It may work if you run the node.js version of breakout server on the Raspberry Pi. You will need to install NodeJS version 10 on the Raspberry Pi first. I don’t have a Raspberry Pi board so I cannot provide support if you cannot get it to work.

I recommend using johnny-five instead which supports JavaScript for Raspberry Pi: https://github.com/rwaldron/johnny-five.

See the raspi-io plugin for johnny-five: https://github.com/nebrius/raspi-io. There is a large support community that can help if you get stuck.
