I tried to connect my max30102, MLX90614 and grove GSR sensor through ADS1115 in separate i2c buses in raspberry pi 4. I successfully created 2 extra i2c buses by following this instructables ...

The Raspberry Pi I2C Multiplexer is particularly useful in scenarios where multiple I2C devices need to be connected to a single Raspberry Pi. For example, in a home automation system, ...

Since the Raspberry Pi I/O pins operate at 3.3V this could connect to the B side, give you the ability to interface with i2c parts rated for lower or higher voltages.

The latest board from the team enables you to have up to 4 I2C busses connected to either your Arduino development board or Raspberry Pi mini PC and is also equipped with Grove Connectors and LEDs.

The Raspberry Pi 4’s GPIO header also supports more connections, with UART, SPI, and I2C interfaces each supported on four additional pins, and with fixed support for clock stretching over I2C ...

The Raspberry Pi dominated the maker scene for a decade. Supply chain problems then brought the high flying to an end. ... and the GPIOs (including 6× UART, 7× I2C, 3× I2S, 2× PWM). ...
