UNO  Mega 2.8 TFT LCD Touch Display Shield V1 With SD Card Socket For Arduino Board Mudle

UNO Mega 2.8 TFT LCD Touch Display Shield V1 With SD Card Socket For Arduino Board Mudle

Product Review (submitted on June 11, 2013):
The back light leds are wired to the 3v3 line through a 100 ohm resistor. When i read the display data sheet, it states that the forward voltage of the leds are 3.2v. I bypassed the 100ohm resistor with a 4.7 ohm 1/8th watt one and the display is nice and bright now. I will wire a small 100 ohm pot in series with the 4.7 ohm resistor to control the brightness as i will be using it in my car. Thanks for a great product. :-)
