This board has a granted public licence on github for 2-chip PCB, so what are you selling then ?
You're selling produced boards or what ?
24 USD per board ? Assembled, without A1 chips or just board and nothing else ?
I checked license for selling.
I'm hust selling PCB and stencil for DIY guys.
24USD per board is chipper than sample PCB making in my country.
It you need many PCB, you need to order it to PCB factory.
But if you need just 5~10 PCB with Stencil, you can save time and money by my item.
