Find the I2C sensor and you want to connect two or three or more people to you when you realize "Oh, this chip has a fixed I2C address, and from what I know about I2C, you can't have two devices in the same SDA/SCL pin with the same address!" "Are you unlucky? You would if you didn't have this cold 9548 to 8 I2C multiplexer!
Finally, one way to reach 8 I2C devices with the same address is to connect to a microcontroller - this multiplexer acts as a gatekeeper, shuttling commands to the selected I2C pin with your command.
Using it is fairly simple: the multiplexer itself is on the I2C address 0x70 (but can be adjusted from 0x70 to 0x77), and you only need to write a byte to the desired number of multiplexed outputs, port, and BAM - any future I2C packets will be sent to that port. In theory, you can have 8 multiplexers, each 0x70-0x77 address in order to control 64 same-i2c-address-part.
Like all of Adafruit's breakthroughs, we put this good chip on top of your breakthrough so you can use it to detect capacitors and resistors on the circuit board, and make use of the card. Some heads are required and once welded can be inserted into a bread plate. The chip itself is 3V and 5V compatible, so you can use it with any logic level.
