The PCA9546A is a quad bidirectional translating switch controlled via the I²C-bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. An active LOW reset input allows the PCA9546A ...
Jan 11, 2023 · Using the PCA9546 I2C multiplexer with Arduino involves wiring up the I2C multiplexer to your Arduino-compatible microcontroller and running the provided example code. If you're curious why you'd need an I2C multiplexer, be sure to check out this guide that goes in depth on working with multiple copies of the same I2C device, which most likely ...
Mar 8, 2024 · VIN - this is the power pin. Since the multiplexer chip uses 3-5 VDC, to power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V. GND - common ground for power and logic.
Mar 8, 2024 · The Adafruit STEMMA QT / Qwiic PCA9546 Breakout - 4 Channel has five JST SH 1mm connectors: 1 input and 4 outputs. There's one port at the end that connects to your I2C controller (there are also breadboard breakout pins if you need them).
