The parts are kept together on a laser-cut acrylic glass for mechanical support.
Splitting into parts is done to make testing and improvements easier. Namely, changing one part is independent of other parts, as long as inputs and output are the same.

The schematics, production files and photos of assembled parts can be found in the folder 1-Hardware.
Software for the micro-controller can be found in the folder 2-Software.
Measurement results obtained using standardized ESD target mounted on large square aluminum plate can be found in the folder 3-Measurements, using the best available equipment at the School of Electrical Engineering and local accredited EMC laboratory (Idvorsky laboratories). Results obtained from measurements confirm that all standardized levels for the current of ESD pulse are within the allowed tolerances (designated with black lines on the plots).
