I2C Hub 1 to 6 Expansion Unit v2.1 is an I2C multiplexer unit utilizing the PCA9548AP chip, capable of expanding a single I2C interface into six channels. By selecting different channels, it allows multiple devices with the same or different I2C addresses to coexist on the same I2C bus (switching via channel polling). The I2C Hub 1 to 6 Expansion Unit v2.1 features an onboard DIP switch for easy adjustment of the Unit PaHub v2.1's I2C address, supporting multiple-unit cascading to connect more I2C devices. Compared to its predecessor, it offers greater flexibility and scalability in parallel I2C device usage scenarios. This product is ideal for applications requiring simultaneous use of multiple I2C devices.

Features:

  1. I2C HY2.0-4P PORTA expansion
  2. Allows multiple-unit nesting
  3. 6 extended Grove ports
  4. DIP switch for I2C address selection
  5. LEGO-compatible holes

Package Includes:

1 x Unit PaHub v2.1

1 x HY2.0-4P cable (20cm)

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
