您是否曾找到完美的 I2C 传感器,但却发现其固定的 I2C 地址会阻止您在同一总线上使用它的多个实例?别担心;CJMCU-9548 1 对 8 I2C 多路复用器可以帮您解决这一问题!

此多路复用器允许您将最多 8 个具有相同地址的 I2C 设备连接到单个微控制器。它充当守门人,将命令与您的命令一起路由到选定的 I2C 引脚,使其成为扩展 I2C 总线的宝贵工具。

怎么运行的: 使用 CJMCU-9548 非常简单。多路复用器本身的默认 I2C 地址为 0x70,但可以调整为 0x70 至 0x77 之间的任何地址。您只需将一个带有所需多路复用输出编号的字节写入此地址,所有未来的 I2C 数据包都将路由到所选端口。理论上,您最多可以使用 8 个多路复用器,每个多路复用器设置为不同的地址(0x70-0x77),从而允许您使用相同的 I2C 地址控制最多 64 个设备。

规格:

  • 界面: I2C IIC
  • 芯片: TCA9548A
  • 可选的 I2C 地址: 0x70-0x77
  • 工作电压: 1.65 伏——5.5 伏
  • 最大时钟频率: 400千赫

包裹包括:

  • 1 个 TCA9548A I2C 多路复用器分线板

使用 CJMCU-9548 多路复用器扩展您的 I2C 功能,并轻松在单个微控制器上管理具有相同地址的多个 I2C 设备。
