## Abstraction
Fabrication of Printed Circuit Boards ("PCBs") is not very economical as the cost of fabrication raises (among others) with size and the amount of layers and addition to thatd often requires:
1. To sign an NDA
2. Restriction on release of important documents (documentation, reference schematics and gerbers).
3. Restriction on releasing the finished product sources if it's using proprietary components
Fabrication of Printed Circuit Boards ("PCBs") is not very economical as the cost of fabrication raises (among others) with size and the amount of layers and addition to that it also often requires to sign an NDA (such as with NXP) and/or restriction on release of important documents (documentation, reference schematics and gerbers) and often the sources product iself (e.g. [OLIMEX RK3328-SOM-1G](https://www.olimex.com/Products/SOM/RK3328/RK3328-SOM-1G))
Which is a limiting factor for Open-Source Hardware (OSHW) development that I want to address.
