I am using a 5.5" Waveshare AMOLED capacitive screen in my workstation, together with a Raspberry Pi 3B. They are powered over USB from Molex, and receive data using IP-over-USB together with an internal USB3 header. It's a great little device at a good price point (about $130), though quite fragile.
The Waveshare wiki page for the device is a good place to start. The screen takes anywhere from 250 to 650mA, using more power to display lighter, brighter pixels.
Console rotation
Write 1 to /sys/class/graphics/fbcon/rotate. To do it from the kernel, add fbcon=rotate:1 to the kernel command line; in Raspbian, this is done by editing /boot/cmdline.txt. This has no effect on Xorg.
