I prefer micropython over arduino language.
Some tools are so simple they can be done with 50 cent microcontrollers, but that lacks
easy reprogrammability.

Would your boards get cheaper with bulk orders?

Sure, that's how the world works. Also, you can reduce the specs. For instance, my controllers
have a USB power converter on board, and a battery monitor and battery for portability -- all that
can be left off. The MCUs for running micropython cost around $2.50 in 100's, so they
might not work out for the simplest tools unless you like the easy reprogrammability.

With that as the one true top priority, you need to be sure how large your number of customers is,
and ditch easy reprogrammability, because that always costs more.

It's normal how these decisions are not black/white, but grey areas.
I think keeping easy reprogrammability available is part of a system's appeal more than
$1 less cost per node.
