Debug your I²C in seconds - not hours!

The I²C Doctor is an embedded diagnostic tool with a display for analyzing the physical state of your I²C application with specific recommendations (in English).

It belongs in the toolbox of every electronics technician who values ​​their time and the quality of their products.

Note:
Since batch #2, the two pin headers are already soldered and must no longer be soldered on by hand :)

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.

A VDD status LED indicates whether power is supplied. Additionally, the integrated 4.7 kΩ pullup resistors 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.

Ideal for prototypes, maker projects, and IoT applications.

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

I tested various SMD grippers and selected the SDK08 as the best combination of size, handling, and contact reliability.

The SDK08 model is suitable for various larger SMD ICs (SOP, SOIC, TSOP, MSOP, SSOP) and is ideal for accessing individual pins for programming and measuring devices such as the I²C Doctor.

Specifications:
- Maximum voltage: 40V
- Maximum current: 2A
- Minimum pitch: 0.3mm

Contents:
- 10x SMD grippers (SDK08)
- 1x Instructions in English and Chinese
