I2C-RPT-01 -6026 CCA-640px.jpg

Features

  • I2C Hub / Repeater / Replicator / Multiplexer / De-multiplexer
    • PCA9544A IC
  • Controlled via I2C
  • Multiple part vendors
  • Devices with the same address can be attached to different ports
  • Host I2 port goes to Raspberry Pi I2C lines
  • 3.3V host operation
  • Four I2C slave ports
  • I2C ports can use the Raspberry Pi or have their own power (power source select jumper)
  • A Raspberry PI which runs 3.3V can control an I2C device which runs at 5V
  • Voltage translation between the ports
  • I2C ports can be 3.3V or 5V
  • Fits in any Raspberry Pi model
  • Cutout for Model B RCA video jack
  • Interrupt controller on each channel and host 100KHz/400KHz operation
  • On-board termination resistors
