This version of HyperPixel comes with an IPS display, for better wider viewing angles, custom made cover glass, and the alternate I2C interface is broken, in case someone wants to poke around.
It comes fully assembled so that you do not have to bother with soldering.
Please note: when installing HyperPixel 4.0 onto your Pi make sure not to apply to much pressure on the screen surface. Hold the board by its edges and carefully connect with the extended header.
Pimoroni has put together a one-line-installer to make the process of integrating the HyperPixel 4.0 to your Pi easier:
Open a terminal, and type
curl https://get.pimoroni.com/hyperpixel4 | bash to run the one-line installer and set your HyperPixel 4.0 up.
