Hi Jean-Samuel,

This is very good news! It means we've met the target cost price and
we haven't compromised functionality.

Could you ask the fab how much would it cost to put the board into an
enclosure like this, including the front panel and the rear panel
drilling and engraving?

The idea is to sell it to general public in small quantities for in-lab use.
