Shield Vs Converter

Other Hardware General Electronics

Hello,

I'm hoping someone can explain to me the difference between a shield and a converter? I can't seem to find any documentation on this, and i genuinely don't see the difference.

For example:
I am currently driving an AB VFD using an RS485 shield on an Arduino Mega 2560:
https://www.amazon.com/RS485-Shield-For-Arduino/dp/B01K84RJUQ/ref=sr_1_6?crid=8XSUODDR636B&dchild=1&keywords=rs485+shield+for+arduino&qid=1610729097&sprefix=RS485+sh%2Cindustrial%2C167&sr=8-6

Looking to do a mass rollout from benchtop to dozens of unit in production, and i found these converters:

So, what's the difference in functionality? apart from the pinouts...

Thank you in advance for your help.

Think of a shield as a product that plugs onto an existing main board, example a shield plugs onto an Arduino UNO.

Hi Larry, i understand the difference in form/fit & appreciate the example. Am i to interpret your lack of addressing the functionality as "there is no difference in function"?

It appears they are just a ‘Transceiver’.

Of course, you need a similar unit at the far end.

And one is ‘ Currently unavailable. ’ ;).
