Features
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. 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. Some header is required and once soldered in you can plug it into a solderless-breadboard. The chip itself is 3V and 5V compliant so you can use it with any logic level.
Details
Are you tired of limited I2C connectivity for your microcontroller? Look no further than the Adafruit TCA9548A I2C Multiplexer [ADA2717]. With this multiplexer, you can connect up to 8 same-address I2C devices to a single microcontroller, making your projects more versatile than ever before.
Featuring a user-friendly interface, the multiplexer acts as a gatekeeper, transmitting commands to the desired set of I2C pins with ease. Simply write a single byte to the I2C address 0x70 (adjustable from 0x70 to 0x77) and your I2C packets will be sent to the selected port. Whether you want to control multiple sensors, displays, or other I2C peripherals, this multiplexer has got you covered.
What sets the Adafruit TCA9548A I2C Multiplexer apart is its convenience. We've designed a breakout board for easy integration into your projects. With the breakout board, you can use it on a breadboard with capacitors, and easily connect it to other components. Additionally, the chip is 3V and 5V compliant, ensuring compatibility with various logic levels.
Don't let I2C limitations hold you back. Unlock the full potential of your microcontroller with the Adafruit TCA9548A I2C Multiplexer. Order now and take your projects to the next level!
