PaHUB

SKU:U040

Description

PaHUB, is an I2C device splitter, which can expand a single I2C HY2.0-4P interface to six channels, and allows to mount slave devices with the same I2C address (by controlling to poll different channels to achieve the same Address device coexistence). Embedded TCA9548A-I2C multi-channel switch IC, supports 6 groups of I2C device expansion.

Note: When working, the splitter realizes the coexistence of devices with the same address by polling different channels. Please pay attention to the channel order when programming.

Specification

Resources Parameter
Communication protocol I2C: 0x70(can be modified by resistance A0, A1, A2)
Net weight 7g
Gross weight 19g
Product Size 48*24*12mm
Package Size 67*53*12mm

Schematic

Referring to the schematic diagram and the TCA9548A data sheet, it can be seen that the Unit can modify the I2C address of the device by controlling the level combination of the A0 ~ A2 pins. (Default address is 0x70)

Three chip resistance welding positions are reserved on the PCB of the Unit, which are A0-A2, as shown in the figure below.

After soldering a 0 ohm resistor, the corresponding pin will change from low to high, and the pin level combination and its corresponding I2C address are shown in the table below.
