Is the Diy pcb version still working?

Hello

Im really intereated in building this vesc, i saw a vid on you tube showing an open source vesc, is the diy version still a working unit?

I found the file on github i see its 4 years old now really hope it does work, is there anything else i have to do / buy?

Also if it does work  can it be used with other controllers out there ?

Thank you
