There are an increasing number of \"bottom (price) end\" processors
like this. I suspect some have \"issues\" that may complicate
their initial use. But, if you treat them as \"programmable hardware\"
(and not something that should be updated regularly) and fully define
their function, they can be winners.

I use a tiny device for hardware signalling to a remote
controller without the cost (power budget) of a \"big\" processor.
Sort of like relying on the nonvolatile timer in your RTC to
wakeup the real processor -- instead of having the real processor
\"counting time\".

I\'m in a Discord with folk who have been using these chips for a couple
of months now. The consensus is that they\'re just fine. Better
documented than most Chinese chips, bit worse than most Western ones,
but nothing dramatic.

WCH can make them so cheaply because they own the IP for all the
peripherals, instead of licensing those from a third party. And because
RISC-V is free, of course.
