In order to stay in the modular "family" design changes have been made. Lets take a look.

If yo can tell there is a "break" in between the "MAIN" module and the other two modules. The way that this will work is like so.

Each module has I/O headers on each side of the PCB making it possible to have the connection to the main board.. driving the LCD is a piZero. We have Headphone output, and a dc jack to provide power to the rest of the board.
