I would like to build the hardware on my own. I looked through the design files but some things need clarification.
– What is the exact type of TVS supressor diodes? I mean the nominal reverse voltage.
– If I do not need analog I/O can I leave out the PCF8591 A/D D/A converter chip? I am afraid if the lack of the chip causes any problem in software run.
Could you plase answer the questions above?
