The promotion of the Nano R4 states that it facilitates the transition from prototype to production. What data backs up this claim? Is this Nano configuration more reliable? Does it have a lower error rate than the classical Nano? Does it consume less power? IS it less susceptible to static discharge? I am seeking data on why this would be a more suitable choice for a production product.
Because something in a Nano footprint is more easily soldered to a PCB than something with an Uno footprint?
Seems a little weak considering all the hype. But you may be correct. I'm not sure about you, but my response is...Not that Big a Deal.
I would say it is. Try soldering an Uno R4 to a PCB
The Nano R4 has a couple of advantages over the UNO style boards. With header pins, it can be plugged directly into a solderless breadboard, and there is nothing mounted to the back of the board, allowing it to be directly soldered to a larger printed circuit board.
Thanks. You are correct. turns out none of us would ever solder it directly to a board for serviceability. When I evaluate a production-worthy component, I consider reliability and other, more complex specifications. Plugging it into a solderless breadboard is a plus.
Why not, you solder other SMD devices to a PCB. I've soldered ESP modules directly to a PCB
Good for you.
I don't thimk you understand. A Nano R4 can be soldered directly to a PCB like any other SMD device whereas an Uno cannot.
I understand, I think it is you who has to understand. When you design a real product, not a toaster controller or some other hacker project, you design at a much higher level, and you consider detailed aspects of the components. Environmental aspects of the components are essential to understand, as is how the operating environment will affect the lifetime of the product. Sustainability and international usage are also considerations.
Being able to solder a nano R4 to a PCB does make it more production ready then an Uno.
However, I would never consider using any Arduino device in a commercial or industrial product. Not sure why you are.
I'm sure it's because Arduino would like you to use lots of them and certainly the form factor is a plus. Their opinion aside, if you were to design one into a product it would at least be wise to make it easily replaceable.
I agree. Thanks for your answer
Remember you can also solder on headers to the Nano R4 and plug it into a socket for easy replacement.
Yes, exactly. I have product using quality Samtec board to board contact products that have lasted many decades in harsh chemical environments with no interconnect failures.
Samtec products are fantastic. I use them for high-pin-count and high-speed connections, and they work beautifully. I have tried others, but I always come back to Samtec when I don't want to compromise on performance.
Thanks for the comment. We do that all the time. The product is designed for easy replacement without the need for soldering or tools. Thus far we have had to replace one processor. This is beneficial, as the product operates 24/7. Our products have a reputation for being reliable and serviceable.
