The first version of the board is completed and ready to etch!
The schematic illustrates self explanatory dashed blocks and a name describing its main functionality. Together they form the whole structure of the "main" board. This acts as an interface between the microcontroller and AE (Active Electrodes, i.e. sensors).
First an image capture of the layout "as it is".
Secondly, we can distinguish the different sections that form the block-structure described above.
New version pending: shield-arduino compatible ...
