轨迹球模块


产品简介


轨迹球模块采用黑莓轨迹球设计制作，模块可以通过滚轮运动传动X和Y方向的转轴，通过固定在转轴上的多极充磁磁体转动,对相应的SMD霍尔元件发出信号,从而确定运动轨迹。轨迹球下方还设计了一个小SMD开关，方便用户进行触发事件或“点击”选择。


规格参数


  • 供电电压：DC3.3 - 5V
  • 安装孔径：3MM
  • 模块尺寸：28*21*15.7MM（长*宽*高）
  • 孔间距：15MM
  • 模块重量：2.5g


引脚说明


名称 说明
RHT Sign - right
LET Sign - left
DWN Sign - down
UP Sign - up
KEY Sign - key
VCC 电源+5V
GND 地
