You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino 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 didn't have this ultra-coolTCA9548A 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 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.
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.
Case is nice and sturdy all ports are perfectly aligned it has enough room for hat , especially if you want use Geekworm X1002 PCIe to M.2 2280 hat for nvme.
The only thing is missing is heat dissipation cut outs on the top of the case , If it has heat dissipation holes on the top it will be much better however case is having many cutout on the front bottom and right side but , for active cooler to release instant heat top side cutout will be much better .
Next thing it will be better If it comes with rubber feet so that in case we don't want to mount on wall we can place on table little bit risen up from the surface.
It comes with rail mount and wall mount which is very good.
with offical RPI5 active cooler and if cooler is not running (only passive heat release)the ideal temp of pi 5 stays around 53 degree Celsius when room's ambient temperature is around 18 degrees , and its running on raspberry pi os .
what will be the temp. on summers that i yet to experience.
