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.
You still didn't answer what are you selling :
a) NAKED PCB
b) ASSEMBLED PCB
c) ASSEMBLED PCB WITH A1 CHIPS
answer is A. :-)
you need SMD components.
I'm selling $24 per board. ( b and c are impossible in this price. )
Why would someone pay 24 USD for bare board from KOREA, when public design is published and transport costs more then it's production ?
If you could scale up assembly price to 24, that would mean something, this way it's a rip-off...
Oh, I don't known your PCB maker's sample PCB production fee.
But in my case, I ordered this PCB before, ( 8pc sample production 4 day deliver ) is was $200. ( $25 per board ).
If you need small quantity (5~10), It almost same price with sample production.
You don't need to wait production time.
If you want over 10 pc, you just make your order and wait over a week for production.
I just think someone need this PCB with stencil for small DIY. (It is not a mass production price.)
