I love the no-nonsense mentality, and quality design behind this approach for
most use cases. But, for some high-reliability use cases like mine -- a device
permanently installed in a remote, client wall — batteries aren’t a great fit.
For long-term accessibility: Battery maintenance, even after years
of initial functionality, is extremely inconvenient or impossible.
For insurance reasons: The potential liability of installing
LiPo, which is known to have potential fire issues, into a client’s wall.
For shipping reasons: The added hassle of international
shipping of LiPo-based systems.

Hardware cost is relative. The “high” cost (<$100) of a system design
is nothing, if it will potentially save me things like panicked client calls,
last-minute international plane tickets and high-pressure field repairs. Those
just aren’t fun. Obviously every project out there isn’t heading to a NASA
rover, but in some lines of work this kind of service is expected when a
high-end, mission-critical system goes down. In the end, if I do my job right,
the price is just passed on to the client who is willing to pay a premium for a
high reliability, maintenance-free product.
I’d like to be able to deploy those systems based on the BBB, because I know
it, find the platform highly versatile, and a good match for the variety of
projects I take on. I think the PRUs especially make this a very unique little
SoC.
Best,
ST
