+ITEAD 2.4" TFT with Touch
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  The Arduino 2.4" TFT Touch Shield is designed for all the Arduino
+  compatible boards. It works in 3.3V voltage level. It can be directly
+  plugged on the Arduino and other compatible boards. It will offer
+  display, touch and storage functions for the Arduino board
+
+  Features:
+
+    1. Compatible with 3.3/5V operation voltage level
+    2. Compatible with UTFT library
+    3. With SD Card Socket
+
+  The Arduino 2.4" TFT Touch shield uses the S6D1121 controller , it
+  supports 8-bit data interface. The touch IC is TSC2046.

+  NOTE:
+
+  1. It is not possible to use any of the SPI devices on the Shield unless
+     a bit-bang SPI interface is used.  This includes the touch controller
+     and the SD card.
+  2. UART0 cannot be used
+  3. Parallel data is not contiguous in any PIO register
+  4. 3.3V and 5V are reversed.
