4 analog inputs

Dear all,
Thank you for reading (and hopefully helping)

I am dealing with one sensor location where I need 4 analog inputs for several sensors.

So far, I have tried working with with 2 5005-base boards, each coupled with a 13002 module. Both boards are connected to the same battery and the same solar panel and it does seem to work wel… I suspect power issues even though the solar panel is of sufficient wattage.

So I thought of another idea (and that is my actual question). Can I use a dual base board 19001 connected with 2 13002 modules? And if so, how would I be able to read the data from the analog pins on the second 13002 boards? Will they automatically become AIN2 and AIN3?

I simple have a dual base board lying around, so could be the easiest solution

Thanks for your help!

Welcome to the forum @duke_theweather

Using the Dual IO Base Board does not solve your problem, because the IO slots are identical. AIN1 on Slot1 is AIN1 on Slot 2.

What voltage do you need on the analog inputs? Is 5V required or would 3.3V sufficient?
If 3.3V works, you could use the RAK16001, which gives you 6 analog inputs with 3.3V.
