The IO Extender for UNIHIKER K10 is a dedicated expansion shield engineered to unlock the full creative potential of the UNIHIKER K10 AI Coding Learning Board. It functions by breaking out all of the UNIHIKER K10's onboard IO pins into a more accessible and feature-rich layout. The core design philosophy centers on providing stable, high-current power for demanding peripherals like servos and AI cameras, while simplifying connectivity through clearly labeled, multi-functional ports. Key features include four dedicated servo interfaces with an independent power supply, a specialized port for the HuskyLens AI Vision Sensor, and full compatibility with the micro:bit ecosystem. This makes the extender an ideal solution for advanced projects in STEM education, robotics, and interactive AI applications.


Stable and Reliable Power for Robotics

A common failure point in complex projects is insufficient power for multiple motors, leading to servo jitter and unpredictable behavior. This extender solves that problem with four dedicated servo interfaces (S0-S3) that are powered directly from the main 5V Type-C input, bypassing the mainboard's regulator. This architecture ensures that up to four servos can operate simultaneously with a stable and consistent power supply, resulting in smooth, precise, and reliable motion for robotic arms, walkers, and other actuated creations.


Simplified and Versatile Connectivity

Every interface on the board is clearly labeled with silk-screen text, eliminating ambiguity and the need to constantly reference external diagrams. This allows for rapid prototyping and intuitive assembly, which is especially valuable in educational settings. Furthermore, the extender integrates four multi-functional C-ports (C0-C3). Each port supports standard analog and digital signals and is also pre-configured for easy data reading from popular sensors like the 18B20, DHT11, and DHT22, streamlining the process of building environmental monitoring systems or data loggers.


Optimized for AI Vision Applications

To facilitate the integration of artificial intelligence, the expansion board includes a dedicated I2C interface specifically for the HuskyLens AI Vision Sensor. Crucially, this port also draws power directly from the main input terminal, providing the sufficient and stable operating current required by the camera during intensive processing tasks like object or face recognition. This ensures the HuskyLens performs reliably without risk of power-related crashes, making AI integration both simple and robust.


Seamless Cross-Platform Compatibility

Designed for maximum flexibility, the IO Extender is fully compatible with the entire micro:bit series (V1/V2). It includes thoughtful features for micro:bit users, such as an onboard passive buzzer connected to P0 and a separate MicroUSB power port. The physical layout of the MicroUSB and Type-C power inputs has been carefully designed with significant spacing to prevent accidental simultaneous connection, mitigating the risk of short circuits and enhancing safety in classroom or workshop environments.
