Adafruit TCA9548A I2C Multiplexer ADA2717

#ad
Adafruit #ad - The chip itself is 3v and 5V compliant so you can use it with any logic level. Using it is fairly straight-forward: the multiplexer itself is on i2c address 0x70 but can be adjusted from 0x70 to 0x77 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 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part. Like all adafruit breakouts, we put this nice chip on a breakout for you so you can use it on a breadboard with capacitors, and pullups and pulldowns to make usage a snap.

Finally, a way to get up to 8 same-address i2c devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command. Some header is required and once soldered in you can plug it into a solderless-breadboard.

We put this nice chip on a breakout for you so you can use it on a breadboard with capacitors, and pullups and pulldowns to make usage a snap. You just found the perfect i2c sensor, this chip has a fixed i2c address, you cannot have two devices with the same address on the same SDA/SCL pins!" Are you out of luck? You would be, and you want to wire up two or three or more of them to your device when you realize "Uh oh, and from what i know about i2c, if you didn't have this ultra-cool CJMCU-9548 1-to-8 I2C multiplexer!.

The chip itself is 3v and 5V compliant so you can use it with any logic level. Some header is required and once soldered in you can plug it into a solderless-breadboard.

Gravity: 12C Digital 1-to-8 I2C 8 Channel Multiplexer Breakout Module for Arduino Raspberry Pi and Micro:bit

#ad
DFROBOT #ad - So powerful. 3. 3~5. 0v wide operating voltage; 3. 3v i2c digital level, and also; compatible with 5V main control board such as Arduino UNO; On-board I2C address dial switch, optimized for 3.

3v main control board such as Raspberry Pi, the I2C address can be set. The default i2c address of the multiplexer is 0x70, you could hook up 8 multiplexers on address 0x70~0x77, and you can adjust from 0x70 to 0x77. On the same i2c port, dfrobot gravity: i2C Multiplexer solves the address conflict and enables the normal communication with multiple same-address I2C devices. In theory, to control 64 same-address devices. This i2c multiplexer is easy to use, plug and plug and no need to weld. 1 multiplexer has 8 i2c ports, this means you can hook up 8 same-address devices at the same I2C port by 1 multiplexer.
