The M5Stack PaHub v2.1 is an I2C multiplexer hub module based on the PCA9548AP, expanding one I2C interface into 6 channels. Its I2C address is adjustable from 0x70 to 0x77 via DIP switch and it supports cascading multiple units. More product details

Product Description

The M5Stack PaHub v2.1 is a compact I2C multiplexer hub module designed to expand a single I2C interface into six separate channels. This U040-B-V21 variant uses the PCA9548AP multiplexer IC and is intended for systems where multiple I2C devices need to be connected to one host.

By switching between channels, the module allows devices with identical or different I2C addresses to coexist on the same bus. An onboard DIP switch provides address selection in the range from 0x70 to 0x77. This enables cascading of multiple PaHub v2.1 units when additional I2C expansion capacity is required.

Technical Features

I2C multiplexer based on PCA9548AP
Expands 1 I2C interface into 6 separate channels
I2C address range 0x70 to 0x77, default address 0x70
Address selection via onboard DIP switch
Supports devices with identical or different I2C addresses
Supports cascading of multiple modules
6 HY2.0-4P/Grove-compatible expansion ports
Dimensions: 48.0 x 24.0 x 10.8 mm

Application Areas

This module is intended for I2C expansion in embedded systems, prototypes, and measurement setups. Typical uses include connecting multiple sensors, actuators, or display modules to a single controller port, especially when duplicate I2C addresses are present. With cascading support, the module is suitable for scalable test setups and compact multi-sensor systems using M5Stack or Grove-compatible cabling.
