The main PCB for Dodo has been complete for awhile now, but the game controller, sound amplifier, game cartridge, and screen mount are still in the prototype phase. I plan to create a second PCB that integrates all of this functionality. This board has less components than the main board, but it has the added complexity that it needs to support having a case with cutouts that fit perfectly so that the buttons can be pushed and the screen sits nicely. This means that the buttons need a height that matches the screen.

I am close to selecting the exact components that I will use for the board. The final piece that is needed is a thumbwheel potentiometer for volume control. Another detail that I am mulling over is how to deal with the solder joints on the top side of the screen. I either need to trim or grind them flush, or have a groove in the case to accommodate them.

The buttons, display standoffs, display mounting header, and card edge connector all seem like they will work well together.
