Hi @Youssif thanks for getting back to me.
Yes, that’s more or less my setup, a 2W instead of a Pico. Regarding power, yes, I need to take that into account, and perhaps feed the Notecarrier X and Notecard separately if applicable.
I’m exchanging some ideas with @RobLauer here in this topic where he mentioned using serial RX/TX instead of I2C.
There are 3 GND on the Notecarrier X, so you say I should connect both the Ada Fruit GPS GND and Pi 2 W GND to the same one in the X?
Thanks,
Henrique
