Respeaker Core V1 - Grove Expansion Driver

I have a respeaker core v1 device and the Grove Extension Board.
I can’t find the driver for the extension board on the site.
How am I supposed to interface with the Grove modules?

Did you ever find the driver ?

basically there isn’t one as they didn’t bother writing one. i guess they didn’t sell enough units to care.

That’s disappointing

not just disappointing but feels like a scam

I am trying to avoid slagging them off too much but I hear you;;
