简介

Mango Uno原理图是基于国产芯片LGT8F328P-QFP32替代Atmega328P(两款芯片的差异对比)而重新设计生产一款可以兼容替代arduino uno的兼容性主板。 Mango Uno特点如下

  • 尺寸接口完全兼容Arduino Uno主板,所有器件采用全贴片,背面平整;
  • 主芯片为LGT8F328P,带外置16M晶振,串口芯片为原装CH340G芯片带外置晶振,精度更高更稳定;
  • 所有引脚引出,预留了焊接位,扩展的I2C, UART, A6, A7接口;
  • 主板的3.3V输出电流可达500mA电流,使得主板可以外接更多的外设;
  • 二极管采用低压SS34可以过电流3A,扩展外部电流时承受更大电流.
