TFT power: the screen power supply is 2.8-3.3V; do not use 5V
 
Backlighting power (LED pin): The backlight power supply is up to 3.2V.
(Module has been connected in series 10 ohm current limiting resistor, LED_A pin can be connected 3.3V, if connected 5V
Need to modify the limiting resistor to 100 ohms, otherwise it will burn the backlight).

Data port level: theoretically the data port level can not exceeds 3.3V, if you want to use 5V ,the IO connection to the data bus. As the tft internal voltage clamp,it can be used, but is is non-standard. You can do experiments or do the sample test, when doing bulk products, in order to improve product stability, it is best to use low-voltage single-chip or add a level conversion IC.
