TI-H: PCB layouts
I've got my layout for the new EL backlight inverter mostly done.
I'm having about 80 of them produced by a PCB company.
However, before I continue with the design, I'd like to get a little
input. I have been considering making the PCB a combination
of devices, instead of just a backlight inverter. I could add on
layouts for external power and spin port circuitry, along with
solder points to provide power for other devices that a user
might want to add. The additional board space is cheap, and
would not have to be used if only a backlight was need.
The advantage here is that it is very easy to add several
devices at once.
Alternately, I could design several separate boards that
can be cabled together and could work with or without
a central power port board (which would also supply power
to the calculator itself). This would be more versatile, and
would result in smaller boards inside the calc.
The ultimate goal is to simplify the addition of new devices
to a calc. Instead of having to custom mount new stuff, it
can be put on a PCB using surface mount components,
installed in the calc and connected to the existing power
system (which may or may not be controlled by a power
port board). This simplifies wire runs and makes for
more professional and reliable devices.
What do you guys think? I'm leaning toward separate boards
that can be cabled together, since its more versatile; in
hardware mods, custom is the name of the game.
