For Bbc :bit V2.2 Development Board Graphical Programmable Python Primary And Secondary Schools Dev

Improved CPU performance The overall hardware performance of the CPU is four that of the original. These optimizations sufficient basic guarantees for subsequent complex interaction and control projects. A capacitive touch sensor that returns a digital signal to the :bit like a button. New speaker In addition to outputting sound through PWM on the pin, :BitV2 also has an onboard electromagnetic speaker that can output sound to complete more experiments. The onboard MEMS package microphone provides sound input for the :bit, and there is a microphone LED indicator on the front. The newly upgraded gold finger can better fix the clip.
