+## Description
+
+**PaHUB**, is a expander for I2C GROVE PORTA(red port on M5Core). 1-to-6. If you want connect mutiple I2C slave devices and some of them may sharing the same address, this unit can resolve I2C address conflicts.
+
+At the Unit PaHUB's heart is an **TCA9548A** produced by TI. The TCA9548A device has eight bidirectional translating switches that can be controlled through the I2C bus. The SCL/SDA upstream pair fans out to downstream pairs, or channels. Any individual SCn/SDn channel or combination of channels can beselected, determined by the contents of the
+programmable control register.
+
+Technically this Unit allows mutiple levels of nesting, for example you can wire PaHUBs to the root PaHUB to get more seats for your I2C slave devices, if you have 7 of them you can have up to 36 I2C GROVE ports, which makes it easier to get your project more organized.
+
+The I2C address of this unit is 0x77 (changable by resistors).
+
+*Notice: Please pay attention to the channel order while programing*
