Stack Grove Pi+ Board for 15 Analog Sensors

1

I have a solar battery monitoring system project that needs 15 analog voltage dividers. Is it possible to stack 5 Grove Pi+ boards and retain a reasonable signal/noise for all analog inputs to function properly?

You can indeed stack the Grovepi (up to 10 is what’s been reported to us!)

We have instructions here: https://www.dexterindustries.com/GrovePi/programming/using-multiple-grovepis-together/

This is very good news! Thanks for the quick response.

I’m attempting a stack of 3 Grove Pi+ boards and programming with Node Red. I have set the firmware on each board with addresses 3, 4, and 5. Do you have any suggestions for how to set up Node Red JSON to read the different addresses?

Thanks for the help!

I’m using the three analog ports on each of the Grove Pi+ boards.
