Bbc V2 Kit Built-in Speaker Microphone Touch Sensitive Programmable Development Board+battery Box D

On-board MEMS microphone, providing sound input for :bit, built-in LED indicator on the front, external bias circuit ( to ground) 33K:1KBuilt-in speaker to play sound In addition to outputting sound through PWM on the pin, :bit V2 also has an on-board electromagnetic speaker, which can output sound to complete more experimentsThe logo on the front of the capacitive touch sensor becomes a metal capacitive touch sensor, which can return digital signals to :bit V2 like a buttonProvide up to 200MA current Built-in discrete voltage regulator chip, which can provide up to 200MA current for peripheral accessories, providing more powerful support for projects such as camel machine controlCompared with the previous generation :bit v1.5, :bit V2has the same excellent and powerful functions. On the basis of the same functions, it adds functions such as speakers and microphones, allowing children to use sound and touch in the classroom.
