Features
- I2C Hub / Repeater / Replicator / Multiplexer / De-multiplexer
- Four I2C Ports
- Host port Controlled via I2C
- PCA9544A IC Multiple vendors
- 3.3V or 5V host operation
- 3.3V or 5V slave ports operation
- Voltage translation between the ports
- Example: A Raspberry PI which runs 3.3V can control an I2C device which runs at 5V
- Interrupt line on each channel and host
- 100KHz/400KHz operation
- On-board termination resistors
- 49x49mm form factor
- 4 solid 4-40 mounting holes
- Arduino driver and example code
- Raspberry Pi example code
Drivers/Example Code
- GitHub Repo - Arduino Driver code
- Github Repo - Example code
Schematic
Testing
- Arduino Based Test Station
- Connects directly to I2C port on the Blue Pill Hub
- I2C address offset = 0x0
- Blue Pill Hub is set to offset=0x1 so it does not conflict
- Uses 4x of I2CIO-8 cards
- ODAS Tester Github Repo
