Well, forget the chinese stuff.
Take this as a reference: http://www.ebay.com/itm/SainSmart-3-2-TFT-TFT-LCD-Shield-for-Arduino-Mega2560-Mega1280-R3-Nano-Robot-/271019836468?pt=LH_DefaultDomain_0&hash=item3f1a0a8434
Does anyone here have such shield? How many available pins will there be left after plugging the shield to an arduino mega?
Thanks.
