Powering up with USB

I had a Nokia 1 plus phone which I've enabled usb debugging before. Months later screen got broken. I still could use it via adb screen mirroring. But some time later battery went dead and I thought better to throw it away. I'm interested in chipsets and etc so opened phone carefully and took motherboard. Now I think is it possible to use it in the same way as Raspberry Pi works. Phones can work without battery and screen can be mirrored to PC. Can anyone help?
