TFT LCD header properties

Name TFT
Reference J3
Type Pin header (2.54mm, 16x2, female)
  • Note: Pin 28 is used for controlling the TFT backlight. It is connected to the collector of Q1. The emitter of Q1 is connected to the +3.3V rail. The base of Q1 is connected to the absent resistor R19. Neither side of R19 is connected to the microcontroller. By default, the base of Q1 is in a floating state, and does not conduct. Pin 28 is pulled down by a 1.5kΩ resistor (R20). To make the signal on pin 28 high, you can either install a 100Ω 0603 resistor as R19 or connect the base to one of the microcontroller's pins through a 1.5kΩ resistor.
  • Note: Pin 29 is usually not connected on the TFT side.
