Unit PaHub v2.0
SKU:U040-B
Description
Unit PaHub v2.0 is an I2C device splitter capable of expanding a single I2C HY2.0-4P interface into six channels, and allows mounting slave devices with the same I2C address (by controlling polling of different channels to achieve coexistence of same-address devices). It is equipped with a PCA9548AP-I2C multi-channel switch IC, supporting expansion for 6 sets of I2C devices.
Features
- I2C HY2.0-4P PORTA expansion

According to the schematic diagram and the PCA9548AP datasheet, this Unit can change its I2C address by controlling the level combination of the A0~A2 pins (default address is 0x70).
The Unit’s PCB has reserved solder pads for three SMD resistors, labeled A0–A2, as shown below.
After soldering a 0Ω resistor, the corresponding pin changes from low level to high level. The level combination of the pins and their corresponding I2C addresses are as follows:
