Yahboom BBC Micro:bit V2.21 Edge Development Board Built-in Speake Microphone for STEM Education
Micro:bit board is designed by BBC which aims to help children at or above 7 grade to learn programming better. Micro:bit board has abundant board resources, including a 5*5 LED metric dot array, 2 programmable buttons, Compass, USB ports, Bluetooth module etc.. It is only pocket size but very powerful. You can programming, customize or control it as well.
The latest Micro:bit V2 board comes with a touchable Logo and MEMS microphone on the front. A speaker is added on the back, so all kinds of sounds can be played without external equipment. The gold finger at the bottom adds a gear design to facilitate the user to better fix the alligator clip. In addition, the 2nd generation Micro:bit board also support sleep mode. Users can make it enter sleep mode by long pressing the reset button, which can reduce power consumption. The most important feature is that the CPU performance of the Micro:bit V2 board is much better than the V1.5 version, coupled with more RAM. So Micro:bit V2 allow users to expand more functions and create more creative works.
