TCA9548 TCA9548A 1-to-8 I2C 8-channel IIC multiplexer expansion board module expansion board
The I2C sensor was found. You want to connect two or three or more devices to your system. When you realize, "Oh, this chip has a fixed I2C address, and from what I know about I2C, you can't have two devices with the same address on the same SDA/SCL pins!" Are you unlucky? You will be, if you don't have this Cold 9548 to 8 I2C multiplexer!
After that, one method can connect 8 identical I2C devices to a microcontroller - this multiplexer acts as a gatekeeper, passing commands to the selected I2C pin and your commands.
Using it is quite simple: The multiplexer itself is for I2C address 0x70 (but it can be adjusted from 0x70 to 0x77), you just need to write the number of multiplex outputs required, port, and BAM - any future I2C data packets will be sent to that port. In theory, you can have 8 multiplexers, each with an 0x70-0x77 address for controlling 64 same-I2C-addressed parts.
Like all Adafruit breakthroughs, we have this good chip breakthrough for you so you can use it for capacitance and resistance detection on the circuit board and make use of the card. Some headers are necessary, and once soldered, they can be inserted into a breadboard. The chip itself is 3V and 5V compatible, so you can use it with any logic level.
We focus on three core product categories to meet diverse market demands:
