Koanhinn BBC V2.2 Go Set Built-in Speaker Microphone Touch Sensitive Programmable DIY Development Board + Protective Case

Integrated MEMS microphone with sound input for :bit, integrated LED display on the front, external bias circuit (to ground) 33K:1K The logo of the front of the capacitive touch sensor becomes a capacitive touch sensor metal, which can return digital signals to :bit V2.2 like a button Provide up to 200 mA. Built-in discrete voltage regulator chip that can provide 200 mA for peripheral accessories and provides more powerful support for projects such as camel machine control Built-in speaker for playing sound. In addition to sound output via PWM the pin, bit V2.2 also has an integrated electromagnetic speaker that can output sound to perform experiments Compared to the previous generation: bit v1.5, bit V2.2 has the same excellent and powerful functions. the basis of the same functions, it adds functions such as speakers and microphones, children can use sound and touch classrooms.
