PaHUB2

SKU:U040-B

描述

PaHUB2, 是一款 I2C 设备分线器, 能够将单路 I2C HY2.0-4P 接口拓展至六路, 并且允许挂载相同I2C地址的从设备(通过控制轮询不同的通道实现同地址设备共存)。内嵌PCA9548AP - I2C多路通道开关IC, 支持6组I2C设备拓展。

注意:工作时,分线器通过控制轮询不同的通道实现同地址设备共存,编程时请注意通道顺序

产品特性

  • I2C HY2.0-4P PORTA 拓展
  • 2x LEGO 兼容孔s
  • 允许多个嵌套
  • 1-6 拓展

参考原理图及PCA9548AP数据手册可知,该Unit能够通过控制A0~A2引脚的电平组合,修改设备的I2C地址。(默认地址为0x70)

在Unit的PCB板上预留了三个贴片电阻焊接位,分别为A0-A2,如下图所示。

焊接0欧电阻后,相应的引脚将由低电平变为高电平,引脚电平组合与其对应的I2C地址如下表所示。

包含

  • 1x Pahub2 Unit
  • 1x HY2.0-4P线缆

应用

  • I2C扩展
