Need two modules on I/O slot J7

WisBlock

Hello,

First, of all, I am using the RAK5005-O base module with RAK4631 MCU.

Here is what I want to do:

I want to access the RAK4631 ADC input pin and use the RAK15002 Micro SD card module at the same time, on the same RAK5005-O base board.

Here is the problem:

If I want to access the ADC input pin, I need to plug the RAK5804 module on I/O port (slot J7) to access the pin. However, if the slot is taken, I cannot plug in the RAK15002…

Here is the solution that I am considering:

Looking at the datasheets, it looks like the ADC input pin and all the pins used for the SD card module are independent, so I had an idea: build a PCB with a custom connector to access both the ADC pins and the required pins for the SD card module.

Is it possible? Is there a better way?

Thank you

Yes, it is possible. You can make a custom PCB to access the ADC pins.
