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. :-)
