Super small IoT weather station, based on ESP8266, with dimensions of 3 cm x 3.6 cm and a thickness of about 2 cm. It can even be used as a key pendant.
In order to reduce the size of this clock, some functions have been omitted, such as one-click serial port downloading, etc., which require external cables for downloading.
Since TX and RX are not used, the 6-pin Type-C port is used for connection. I think the space is almost fully utilized (haha), but if I have the opportunity, I will try to reduce it. . .
Since I am learning 3D drawing, I asked a friend to do the acrylic engraving this time. I didn’t understand his file, so I didn’t test it and just used it. I will put his file in the attachment. Friends who understand can try it on their own.
