Overview
********

RK043FN66HS-CTG is a 4.3 inch TFT 480*272 pixels with LED backlight and
capacitive touch panel from Rocktech. This LCD panel can work with several i.MX
RT EVKs and LPC MCUs for evaluation of applications with display.

More information about the shield can be found at the `RK043FN66HS-CTG product
page`_.

This display uses a 40 pin parallel FPC interface plus 6 pin I2C interface,
available on many NXP EVKs. Note that this parallel FPC interface is not
compatible with the MIPI FPC interface present on other NXP EVKs.
