In terms of hardware interface, a Phico D0 series module usually features a 14-pin or 16-pin header. Pins 1 through 6 handle power and control signals—specifically Ground, VCC (usually 5V), Contrast Adjustment (V0), Register Select (RS), Read/Write (RW), and Enable (E). Pins 7 through 14 comprise the 8-bit data bus. If the module has 16 pins, the final two pins are dedicated to the LED backlight anode and cathode.
