Note: QMP sold after 1 May 2013 have a newer version
of the Newhaven 2.4" LCD. At this moment, you can use the
above demo by simply replacing the
display driver with this version for the new ILI9340

Usage Notes:
|
VIN supply voltage should not exceed ~5 VDC.
|
When powered by USB, VIN is 5 VDC. |
|
Powering the Quickstart directly with a 9V battery would
exceed the backlight current limit and damage the display.
|
|
It is probably safe to use power from 4 AA or AAA cells
though as that is about 6 V but goes through a diode, which
would drop it a bit. |
