怎麼運行的

 

該套件由連接板和多個傳感器模塊組成。

 

連接板是微位置主板和傳感器模塊之間

的橋樑。

 

它將微位置連接器轉換為服務器

E-brick

連接器。

 

傳感器模塊可以通過

電纜連接到它。

 

How it works 

The kit is composed of a connect board and several sensor modules. The connect 
board is a bridge between the micro:bit main board and the sensor modules. It 

converts the micro:bit edge connector into serveral E-brick connector. The sensor 

modules can be attached to it by cable.
