I2C-RPT-08
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
- 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 8x of I2CIO-8 cards
- ODAS Tester Github Repo
