This question appears to be gathering close votes for the reason "This is a user-level question, not about electrical engineering."
Are we banning discussion of electronic modules used in electronic designs?
If so, let's go through the list and make sure to close questions discussing bluetooth, ethernet, wifi, and microcontroller modules. Also we should ask anyone presenting a question to the site whether they are using a module or not, so we can make sure we aren't supporting people who aren't "real" electrical engineers.
I don't understand the rational behind this decision, but if we're going down this route let's at least be consistent.
