Communications play an incredibly large role in our society, with millions of messages being sent around the world every minute in our wonderfully modern world. And as communications technologies advance, they bring world-wide change that impacts almost every living human on the planet, which demonstrates just how important communications are.
This is why we get so excited with each new product we add to this category, as these modules and components allow us to communicate in brand new ways, enhancing the ways in which we communicate with each other, with strangers, or even with the world around us. However, as avid Makers with years of experience, we also know that communications modules can be some of the most difficult beasts to tame in electronics, and so we’ve hand-picked an excellent selection of communications modules that are both affordable and “tamable” for typical enthusiasts.
Just remember, however, that even the easiest of these modules and components will not necessarily be “easy”, but can be mastered with a good amount of research and some trial and error. Once you’ve mastered these kinds of modules though, the possibilities for building comprehensive, multi-platform communications projects are endless, with some of the most practical examples including projects like adding WiFi to air-conditioning, connecting your kettle to a WAN access portal, as well as building your own customised access control, to name just a few of the exciting projects we’ve seen customers enjoy over the years.
