Mmmm no, I am not from design. Design is my everyday hobby, so far. Not enough knowledge yet, one must successively make his way to the design world.
Don't know about them, but I would have checked what documentation is available and then figured whether it was worth my time to hack it or best look at something more professional
Thats true, I can't complain about that. It successfuly completed our objective, which was mostly just to "test it" and see, where it gets you. I kinda haven't expected so much scattered documentation. I am used to use standard more-or-less of the shelf parts, which mostly have accessible complete documentation, which can be simply applied and the product used.
Maybe I overreacted a bit (it happens, I am bit of choleric person; luckily no hammer is never near me bcs I would widlarize stuff rather quickly), after going through some tens of pages, one can learn anything he needs about the ESP. Then it is really no hard process to deal with the traps the module throws at you.
Ultimately, if it works, it works fine or fine enough that it is a good value for the money. Hopefuly I'll work out some handy usage for the module.
zapta: By mentioning the reliability.. tommorow I'll conduct a consuption analysis. I suspect the other module is somewhat damaged, it got hot rather quickly. It worked, but the operating temperature was interesting. My module I have here on the table doesn't get even near that hot when operating. It is only warm. I will share the results.
