1·The first design is by a large number of peripherals and CPU on a chip in the computer system, smaller, more easily integrated into a complex and demanding on the volume control device which.

最早的设计理念是通过将大量外围设备和CPU 集成在一个芯片中，使计算机系统更小，更容易集成进复杂的而对体积要求严格的控制设备当中。

2·In addition, integrated analog peripherals are fully functional at supply voltages down to 1.8v. This can help simplify design as well as helping to minimize overall power demand.

此外，片上集成的模拟外设的正常工作电压降至1.8 V，这有助于简化应用设计以及最大限度降低整体功耗需求。

3·The board communicates with computer through the Universal Serial Bus(USB) by using CP2101, a highly-integrated USB-to-UART bridge chip, which can realize PC peripherals plug&play.

采集卡利用一种高度集成的USB转UART桥接器CP2101芯片实现了通用串行总线（USB）接口方式，可实现计算机外设的即插即用特性。
