Does work, but hard to get working.
For 4.0" 480x320 IPS screen for Raspberry Pi
You have to use their precompiled kernel which make it useless if you need any other custom drivers.
Documentation about protocols and pinouts are hard to find or does not exist.
The touchscreen was the only thing that worked out of the box. (But had to reverse an axis)
State of front bottons can only be accessed from C code.
Good if you want a touchscreen on your raspberry pi, don't need to compile your own kernel and like programming in C.
