3.3
Different LCD Boards have different power consumption. The subsections below list the different LCD
boards’ current consumption. The number given is the combined current consumption of the +3.3V and
+5.0V supplies. It is the current consumption that is needed from an external +5V supply (when
connected to the OEM Base board).
3.3.1
When using the 4.3 inch LCD together with the LPC1788 Developer’s Kit (LPC1788 OEM board plus
OEM Base board) the current consumption on the +5V (external or USB powering) is about 480 mA.
Note that this is close to the limits of many USB Host ports. Therefore an external power supply might
be needed. A +5V, 2A external power supply is recommended since it then can be used for other LCD
boards also.
3.3.2
When using the 7.0 inch LCD together with the LPC1788 Developer’s Kit (LPC1788 OEM board plus
OEM Base board) the current consumption on the +5V (external or USB powering) is about 1400 mA.
Note that this is way more than a USB Host port can supply. Therefore an external power supply is
needed. A +5V, 2A external power supply is recommended.
3.4
Note that the LCD Board has not been designed for integration into an end-product. It is for evaluation
and prototyping.
