Yes. It has it’s own processor and firmware. It just sends codes and commands over serial between the Printer Controller Board and the LCD. Just connect Tx, Rx, 5V, and Gnd.

And you can slightly modify the interface with custom codes, and custom button images:

Correct, you don’t need to use anything else except TX RX 5V GND for smoothie.
