Hi dear,
The stalker better to use the latest version, but it is up to you.
Anyway, there are compatible with each other but we haven’t have any example for your project.
Another thing is base board can supply 5v to sensors but if you use some sensor to receive analog voltage it just only can read 3.3V to the chip.
So it depend how you use it.
Hope can help you.
Best regard,
Yuri
