+
+The LCD-PAR-S035 is a 3.5” 480x320 IPS TFT LCD module with wide viewing angle
+and 5-point capacitive touch functionality. The LCD module can be controlled
+through either SPI or parallel (8/16bit) 8080/6800.
+More information about the shield can be found
+at the `LCD-PAR-S035 product page`_.
+
+Requirements

+
+This shield can only be used with FRDM-X evaluation kits with a parallel LCD
+connector or a PMOD connector. Currently only the parallel LCD connector is
+enabled.
