PaHUB2

SKU:U040-B

Description

PaHUB2, is an I2C Expandable Hub, which can expand a single I2C HY2.0-4P interface and connects up to 6 I2C channels. It allows you to mount slave devices with the same I2C address (by polling control the different channels to achieve in-device coexistence). Embedded PCA9548AP-I2C multi-channel switch IC, Save you worries with insufficient I2C interface of the expansion.

Note: When it's connected, the PaHUB2 will be polling control the different channels to achieve in-device coexistence. Please pay attention to the order of channels when programming.

Product Features

  • I2C HY2.0-4P PORTA expansion
  • 2x LEGO compatible holes
  • Support multiple nesting
  • 1-6 expansion

Please refer to the schematic and PCA9548AP data manual, the Unit can modify the I2C address of the device by adapting the level combination of A0~A2 pins. (The default address is 0x70)

3 Position of Welding patch are reserved on the PCB board of the Unit, A0-A2 respectively, as shown in the figure below.

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

Include

  • 1x Pahub2 Unit
  • 1x HY2.0-4P Cable

Application

  • I2C device expansion
