8-channel I2C Multiplexer PCA9548A

With this small board, you can control up to 8 I2C devices on a single data line! Even if the I2C devices all have the same I2C address, they can still be controlled individually with this 8-channel PCA9548A. (Also known as TCA9548A, which works the same way)

This multiplexer creates the following addresses:

0x70, 0x71, 0x72, 0x73, 0x74, 0x75, 0x76, and 0x77.

The corresponding pins are:

0x70 -> SD0/SC0
0x71 -> SD1/SC1
0x72 -> SD2/SC2
0x73 -> SD3/SC3
0x74 -> SD4/SC4
0x75 -> SD5/SC5
0x76 -> SD6/SC6
0x77 -> SD7/SC7

Controlling multiple I2C OLED displays

It is possible to control multiple I2C OLED displays using the I2C multiplexer. With one PCA9548A, you can control 8 OLED displays.

Controlling multiple 1602 LCD displays via I2C

Controlling multiple 1602 LCD displays is possible by equipping the 1602 displays with an I2C LCD adapter board. Alternatively, it is also possible to purchase 1602 LCD displays with a pre-soldered I2C adapter.
These displays can then be controlled via a single I2C data line. Here too, the maximum is 8.
