Hrmmmm! You have my attention.<br>
I have used JLCPCB in the past, but was not aware of affordable
component mounting service.<br>

<div class="">I just wanted to pop in and put in a good word for
LCSC. I use <a moz-do-not-send="true" href="http://LCSC.com"
class="">LCSC.com</a> and <a moz-do-not-send="true"
href="http://JLCPCB.com" class="">JLCPCB.com</a> daily for
work, with jlcpcb now having -insanely- great deals on low
volume smt assembly. I'm talking 20 units covered in surface
mount components for ~$3 a piece. jlcpcb already got all of my
business for prototype pcbs before this service went live in the
US, but now I get any prototype pcb for less than I would have a
year ago, with all or most surface mount soldered. A bit of a
game changer for us. </div>

<div class="">I believe<span class="Apple-converted-space"> </span><a
moz-do-not-send="true" href="http://lcsc.com/"
class="">lcsc.com</a> is a reputable distributor, and
the company behind those cheap MCU’s (Paduak Tech) seems
to give reasonable support. There are some <a
moz-do-not-send="true" href="http://eevblog.com/"

discuss their experience with these chips. I just
checked that particular MCU and it is still in stock,
over 18k pcs: <a moz-do-not-send="true"

It boggles the mind…</div>

<div class="">For a more well known example: For a recent
production run I needed 100 pcs of the STM32F103RBT6, a
64 pin Arm Cortex-M3 controller. It is US$1.5348 at
lcsc, and USD 4.83 at Digikey. There is some sort of
supply chain advantage there…</div>

interesting. In general, not for me personally (wrt
applicability). Those seem more primitive than I was aware
still exist, if I read that right you need to chose
whether it comes with an arm OR a leg ;) Which would be
just right for what Richie B. mentioned, e.g. electric
toothbrush, I get it. Wasn't even aware those had MCUs
now... But I guess one step to be "ahead" (marketing wise
anyway) of the competition at some point in their
evolution was to give toothbrushes more than one function,
and as soon as it has that, some simple MCU like that
comes in handy. (or if the charging logic can also ditch
some "traditional" components if a MCU is present, then
it's benefitial even earlier?)<br class="">

perception of 8 bit MCUs fading away comes from seeing a
lot of areas where there once were king, and anything
better prohibitively expensive, and nowadays those fields
that I am more aware of tend not to be so focused anymore
on "lowest end MCU possible" (again, from industrie
examples I stumble upon, which is biased by my particular,
if not peculiar, set of interests, I guess)</p>

summarize, my perception is still that they are becoming

through this thread I have become aware of areas that

all involved.</p>
