The schematic is in the datasheet for the Basic Atom Pro 24M module in the files section.
It is just an RS-232 voltage level translator for the flash loading port and a few other
things (what you call "glue" circuitry).
You could put the all the extra circuitry on the PC to save a few bucks but use up a lot
more space. My guess is by the time you get done getting all the extra parts then add
labor, it would end up being more expensive than just buying the module.
Two options, build what is now on the module carrier board in surface mount into the
main PC board using through hole parts. Or just use the Basic Atom Pro module as a space
saving sub-assembly already tested for you.
The guys at Basic Micro have made no effort to hide any design information. They are
incredibly open with their design and support (for a shoestring operation).
