Voice Needed! How about a Wio Terminal Expansion Board

Hi community,

We got a new product proposal from maker Yan who suggests that us add his Wio Terminal Expansion Board to our official store. His design comes with:
-17 Grove Connectors
-Pin headers to add more expansion boards

What do you think of this design? Shall we manufacture and sell it in our official store? Any price suggestions for this product? Please do let us know your feedback. Thank you so much!
