I wonder which files/folders in project I must share to send a project with someone else?
Along the same which files must I backup with git ?

I notice Mouser no longer has this kit and says
"End of Life: Scheduled for obsolescence and will be discontinued by the manufacturer."
Anyone know if a new kit is scheduled ?
