Thank you Thomas for the clarification. The clarification and reworded section confirm and clear up that confusion.
re: 'Are they really too expensive to just buy and try out?'
Well, that was the reason for the post to start with. Attempting to get validation on how to determine whether the board I have would install the IDE, or will I need to purchase yet another, say the Neonoius board as well.
low.js Professional vs Neonious one + low.js Professional
I guess one technique would be to flash a version of Arduino over this now working low.js and use their functions to get at the available Flash, then re-flash with low.js Each time I perform this task, time consuming and 'bricked' adverse.
It just seems to me that there should be an easier means. I just don't
want to make the assumption that the command:
'To flash, call lowsync flash --init --port=theport --pro --pro-key=thekey'
will gracefully exit should there not be enough onboard Flash. I'm also concerned with this statement:
'The key is only valid for the first device you use it on'
Should I attempt to flash low.js Professional and the board I have doesn't have the 16MB required, what happens? An aggravating message which indicates the board doesn't have enough available flash maybe, which means I'd then have to seek out yet a different board, or try to negotiate a lower price for the Neonious one + low.js Professional combo, as I now have a paid version that is not installable, and the order page doesn't provide a Neonious board option without low.js Professional. I have more than enough flavors of micros in my arsenal as it is.
So at that point, just to 'try out' is in fact too expensive in both part cost/S&H and unrecoverable waste of time.
I would much rather flash the IDE/Debugger on a full blown development board, such as the ESP32-Ethernet-Kit Board with POE, with this one per device requirement. But that is also price adverse just to test out whether the NeoniousOne family is suitable for the project direction I wish to go.
