Thank you to think about it :)
I think it's fine...
I already decrease PCB price to 3Euro each, good surprise for everybody ;)
Black color and ENIG finish:
Mouser total order is around 200Euro for the 8 packages.
And I will order some cables from ali or amazon like this:
cut it and use only female sides. Easier, clean and it will decrease the breakout cable price too ;)
Then it's ok. After ordered everything It will permits me to calculate and ask you the right price, not less and not more...
But, again, thank you for thinking about it
