I have been trying to setup ultra low cost rdp clients program for schools using RPi Zero 2w. This is mostly a hobby/community help project. Majority of schools in my area are either not required with computers or they have lots of older ones with no funding to maintain our modernize them. I'm trying to setup everything within VPN (either wireguard or tailscale). I'll most probably go with tailscale so I can use the subnet router. The zero would would run the older RPiOS (32 bit) and would autostart a rdp session using xrdp client. It's pretty usable for mostly static work that students need in schools. Each RPi unit would cost around ₹2500 ($29) which includes all the adaptors, power supply, sdcard etc. On the server side I'm running two Ubuntu server OS VMs (inside proxmox) configured with XFCE4 and KDE. The work is still in progress, I'm yet to iron out major bugs.
