Decided to just do SOMETHING. Can always make another board down the road.
This version is just plain vanilla. The only difference is I brought out the RS232 lines.
Hope to have this wired in next weekend - work gets in the way of having fun.
Here's the etched board.
Here's the partially stuffed board installed on the LCD. Some SMT stuff on the back for convenience. Regulator is at the bottom if I decide to bolt it to a case to heat dissipation. Should be enough room for a small heatsink.
Front side view - the rear board is the same outline as the LCD.
I was going to use a slimmer LCD (has 2x7 terminals on the side instead) but I'm pretty sure it's an older one that takes 150mA just for the backlighting. This one is < 20mA.
