Hi there :-)
I found several topics and posts but could not find this specific answer, please excuse me if it seems simple but I'm trying to understand everything in order to anticipate my budget
I'd like to assemble 4 trill squares and 2 trill bars using the expansion hub.
The board will be RPi 4 because it's what I've got at home.
I understand they need unique I2C adresses (I read the how-to page about that).
Question is : once I plugged the grove to grove cables in order to regroup my 6 trill sensors to the expansion hub, how do I connect the expansion hub to the RPi board ?
--> all I can see on the board are those GND / VCC / SDA / SCL spots below the grove connectors : do I need jumper wires in those and connect them to the board?
