The “I” socket is an I2C bus or? If I remeber correctly I can add multible “clients” on the I2C using the 3 lines SDA, SCL and ground.
It would therefore be possible to build an module that has multible “I” sockets and I can connect all my sensors there. And only one “I” connector to the mainboard.
A simple driver that handle the adresses of the clients connected to the module and thats all.
If this works the way I imagine this would be a very useful module.
Or maybe I’m totaly wrong.
