The easy way to connect all your I²C devices!
The I²C Hub expands a single I²C bus to up to ten connectors, making it particularly easy to connect multiple sensors, displays, and other I²C modules.
Why did you make it?
To make it as easy as possible to connect and test multiple I²C devices on the same bus, and as a handy accessory for the I²C Doctor when more connectors of the same type are needed.
What makes it special?
Unlike most I²C hubs, it provides multiple connector types on a single PCB. It also features a VDD status LED to indicate whether power is supplied, and integrated 4.7 kΩ pullup resistors that can be enabled or disabled as needed via a 2-way DIP switch. This is especially useful when no pullup resistors are available on the I²C bus yet.
Specifications:
- 4x GROVE/STEMMA connectors
- 4x QT/Qwiic connectors
- 2x 2.54mm pin headers (male & female)
- VDD status LED (green)
- Switchable 4.7 kΩ pullup resistors via DIP switch
- Compact design: 40 × 25 × 12 mm
- Weight: 6g
- 4x 2mm mounting holes, each 3mm from the edge
