People should respect the spirit of open source and sharing, there are so many kinds of arduino modules here(so, nothing relate to
I've purchased a sensor shield v4.0 and a few of the modules. I see on E-bay that there are several Asian vendors now selling these products.
I like the concept very much, but have a complaint. I have not seen one vendor yet that publishes the actual schematic drawings of the sensors boards. If you/they really had a clue about the open source spirit you would be publishing the schematic and board layout files for the sensor modules. One should not even have to ask for such basic information for the people most likely to buy these products.
I guess you/they just assume one treats them as plug and play components with no thought that someone might want to modify the design or just want more detailed information on how they work. Many do come with published simple software examples showing how to use them in a sketch, but as far as information for the hardware not much information or specifications at all. One example is the little audio mic/amp sensor that plugs into a analog sensor port, not a clue on how they are processing the signal and if they are rectifying and/ or filtering and/or biasing the audio before sending it the analog port.
So again I like the concept, it is a step up from basic prototyping on a solderless breadboard, but still simpler then designing ones own custom PCB boards. I just wish more details were available, much like the Arduino folks did from the start with their design.
