100% Brand New and High Quality.
Shape: Same as the picture show
1. Size: 31.5mm x 22mm
2. Type: CJMCU 9548 TCA9548A
3. A way to get up to 8 same-address I2C devices hooked up to one microcontroller.
4. This multiplexer acts as a gate keeper, shuttling the commands to the selected set of I2C pins with your command.
5. 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.
6. 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.
7. The chip itself is 3V and 5V compliant so you can use it with any logic level.
