Features

  • I2C Hub / Repeater / Replicator / Multiplexer / De-multiplexer
    • PCA9548A
    • Eight I2C Ports
    • 100KHz/400KHz operation
  • Host port
    • Controlled via I2C
    • 3.3V or 5V host operation
  • 3.3V or 5V slave ports operation
  • Voltage translation between the ports
  • Ex: a Raspberry PI which runs 3.3V can control I2C devices which run at 5V
  • On-board termination resistors
  • 49x49mm form factor
  • 4 solid 4-40 mounting holes
