## Description

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**](https://i2c-doctor.com) 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
