The Picoclick is a tiny device which can be used as an IOT-Button. It is a one-button-device which let's you control different stuff in your smart home or the internet of things. A basic example is to toggle a light bulb by a button press. Moreover the Picoclick-C3 can be used as a mini development board, because it comes with an FPC extension port where other hardware can be connected to - even I2C is possible.

The Picoclick is an ultra low power device, it only consumes 2μA of current in idle state, which is only due to the embedded battery protection. Most standard protection circuits uses double of that. Without the embedded battery protection we are at 200nA (!!).

The video explains at least the most important parts of the Picoclick project. Furthermore it shows the whole Picoclick evolution and the assembly process of the C3. There are a few examples in the end of the video - including the motion extension board. This extension board comes with the LIS3DH accelerometer and communicates with the Picoclick over I2C.
