I2C Hub 1 to 6 Expansion Board Grove I2C Interface TCA9548A Module

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 0x70 changable by resistors Notice Please pay attention to the channel order while programingProduct Features I2C GROVE PORTA ExpanderTwo Leigo compatible holesNested allowed1 to 6Product Size 48 2mm x 24 2mm x 11mmProduct weight 6 7gLearn The connections of the I2C data path are controlled by the same I2C master device that is switched tocommunicate with multiple I2C slaves After the successful acknowledgment of the slave address hardwareselectable by A0 A1 and A2 pins a single 8 bit control register is written to or read from to determine the selected channels Packageincludes 1x PaHUB
