Feature You just found the perfect I2C sensor and you want to wire up two or three or more of them to your when you realize Uh oh this chip has a fixed I2C address and from what I know about I2C you cannot have two devices with the same address on the same SDA SCL pins Are you out of luck You would be if you didnt have this ultra cool CJMCU 9548 1 to 8 I2C multiplexer 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 com mands to the selected set of I2C pins with your com mand 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 you could have 8 of these multiplexers on each of 0x70 0x77 addresses in order to control 64 of the same I2C addressed part We put this nice chip on 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 Package includes 1 x Expansion Board
