## 4. Design and prototype printed-circuit boards for all candidate solutions
All considered solutions are prototyped. Since some candidate solutions share some components or parts, PCBs/protypes are made for functional parts that can be mixed and matched between O-ESD solutions. For all considered parts that have PCB, gerber and drill files (needed for the production) are given. The photos of prototypes, functional parts and considered components are provided, too.<br>
