The asic chip embedded with bluetooth is usually employed as keyboard mouse equipment controller at present, so that is complicated and expensive to realize. noteworthily a new style of design is developed in the article : a 51 mcu is employed as keyboard mouse equipment controller while controlling bluetooth module as host, which give full play to 51 mcu and make the product at low cost, the design has sure practicability and innovative ; the software of pc end is designed as operating in the backstage, which receives data from usb interface to simulate the function of the keyboard and mouse. the design is easy, the thought is ingenious
由於目前常見的藍牙鍵盤鼠標設備控制器都是用嵌入藍牙核的asic晶元實現，所以實現復雜而且價格昂貴，而文中設計獨辟蹊徑：用一片51單片機
作鍵盤和鼠標的微控制器，
兼作控制藍牙模塊的主機，充分發揮了51單片機的性能，實現了低成本設計，具有一定實用性和創新性； pc機端軟體則設計為運行在後臺的應用程序，接收usb介面數據並進行處理，以模擬鍵盤鼠標功能，這一設計簡單易行，思路巧妙。
