It is a good product for IoT projects, but for me, when I tried to connect it to the wifi using a relay, it did not connect.
For what it does, it's excellent. Also, despite being the simplest model, it's the most convenient to connect to a PCB. Programming with Arduino or RPi and Arduino IDE and good constructions! In Greece, it is sold for an additional €3 compared to AliExpress, for example
