I have Sainsmart's 3.2 TFT and the TFT Mega shield, sitting on top of my Arduino Mega.
Because I want the display to be ~15cm away from the Arduino, I buyed an IDE male-female, 40 wires ribbon cable.I believe it is 28AWG wires so I though it would work but...
It doesn't work, the backlight isn't bright like when plugged directly on the shield, instead it is very very low, I would say 5-10% of the normal light... What is the problem?
Did I just waste my money because an IDE cable can't handle the 5V required by the display (3.3V required by the backlight) ? I measured resistance between the 2 ends of some wires, multimeter show ~0.8 Ohms for each.
