TCA9548A multi-channel Expansion Board Module

TCA9548A multi-channel Expansion Board Module(8-channel IIC development board)

Description

Using it is fairly straight-forward: the TCA9548A multi-channel Expansion Board Module itself is on I2C address 0 x 70 (but can be adjusted from 0 x 70 to 0 x 77) and you simply write a single byte with the desired multiplexed output number to that port, and bam-any future I2C packets will get sent to that port. In theory,you could have 8 of these multiplexers on each of 0 x 70-0 x 77 addresses in order to control 64 of the same-l2C-addressed-part.
