Picoclick: Small and simple IoT button

Picoclick is a simple IoT button in a very small package. The size of the PCB is only 18x20mm, and the height with the 300909 battery is only about 10mm. It's able to connect to your local WiFi at an impressive speed of about 1.5 seconds on average. Yes, since it calls IOT-Button, it uses WiFi of course! This opens up countless possibilities for that little device.

The original idea behind it was to control local lights, sockets and radiators in my smart home by pressing one or two buttons or holding a button... because Picoclick **does not use deepsleep** it enables many possible buttons combination, since the button isn't connected to the MCU's reset line, like it's mostly done on such devices (even on my own old dashbuttons...). That being said, Picoclick can certainly be used elsewhere! I've successfully integrated it into MQTT and IFTTT, but it can be used to control anything that at least has a WiFi connection. Additionally, it has four external GPIOs that can be used to control things and read sensors for other projects. By the way. The Picoclick can flash with that sexy USB-C jack because it has an onboard CP2102N USB-serial bridge.
