The Arduino Engineering Kit Rev 2 is a versatile and practical learning tool. By creating fun, real-world projects, you can understand basic engineering and mechatronics concepts and learn to program in MATLAB and Simulink. The versatility of the elements gives you the opportunity to adapt the content and create your own curriculum based on it. The kit includes online courseware, step-by-step instructions, lessons and exercises. It works best when studying in small groups.

You can easily control any device over the Internet through your phone, computer, etc.
The module can handle 5 users at the same time, it can work in two modes: STA (client) and AP (access point).
In AP mode, the module is connected via WIFI directly to your phone or computer (in open field can be up to 300 meters).
In STA mode, the relay module is connected to the access point (router) that supplies the network.
