DollaTek TCA9548A I2C IIC Multiplexer Breakout Board 8 Channel Expansion Board

I have been testing the AS5600 rotation sensor which I am going to be using on a project, the sensor has a fixed address which means that only one of the devices can be connected at a time, this caused me a problem because I needed to connect 3 at once.This multiplexer takes i2c clock and data and breaks it out to 8 channels. This device (the multiplexer) appears on the i2c address 0x70 and has a register that allows you to enable and disable specific i2c channels.This allowed me to put an AS5600 on 3 different channels, and I can then simply select which i2c bus is active at any time and read the information from the sensor. You can have multiple "buses" connected at once, but in my case I simply needed one at a time so that I could read all 3 sensors as if they were the only connected device.It's a really good device for this kind of situation and works perfectly, it's also incredibly easy to drive so there's no tedious writing of drivers for it before you even get to the meat of your project.Good board. Good device. Good value!

I use this board to allow me to use 6 OLED screens on a panel I am making for DCS F18C flight sim. Have tested the board with 5 screens working on a breadboard. Not enough room for the 6th screenon the breadboard. Worked perfectly. Now I just need to finish building the panel !!
