产品概述
奥松机器人推出的LCD 12864液晶摇杆扩展板采用全新12864G-0088液晶屏为主体显示器件。此扩展板采用Arduino叠层板设计理念，可直接插接到Arduino UNO、Arduino mega328、Arduino mega2560、Arduino ADK控制器上使用，可以清晰显示中文、英文、字符、图片等；板上添加五向微型摇杆，方便实现人机互动；同时本板还具有5个模拟扩展接口和8个字扩展接口；其中各数字接口均分别用黑色、红色、黄色排针来区别电源地、电源正极和信号IO管脚；即方便操作又具有防呆的作用；而且扩展接口可连接各种传感器模块，如温度湿度传感器、三轴加速度计等，是制作显示互动作品不可获缺的显示器。
