Thus far in the book, we have learned how to use two versatile component systems to build electronic projects quickly and easily without soldering or complicated connections. We saw many examples and five projects that demonstrated how to use the Qwiic and STEMMA QT systems.
Both systems provide a vast array of modules, and given they are compatible (can be interchanged with the same cables), these systems are very powerful and an excellent base to build IoT projects. However, these systems restrict you to a single protocol, and while the list of modules supported is long, there are other protocols ...
