Really good multiplexer!
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!

Guter kompakter Multiplexer
Die Verpackung ist, nicht wie von AZ-Delivery üblich, mit einem Umkarton geschützt sondern ungeschützt in einem Kunststoff-Beutel. Die Stiftleisten gehören zum Lieferumfang und müssen auf die Länge angepasst und Benutzer selbst angelötet werden. Der kompakte Multiplexer stellt 8 I²C-Ports (Adresse 0x70 - 0x77) zur Verfügung und auch mit der Betriebsspannung von 1,8V - 5V sind keine Hindernisse in Sicht. Funktioniert...also gut :-)
