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.

Assembling front pane

  • Insert AMOLED into brace by slowly pushing it down
  • Insert micro-USB touch input bridge into AMOLED
  • Mate Raspberry Pi to AMOLED via touch input bridge
  • Insert HDMI bridge into AMOLED and Raspberry Pi
  • Insert angled micro-USB cable into Raspberry Pi
  • Insert straight micro-USB cable into AMOLED
  • Insert Ethernet cable into Raspberry Pi
