Robotics & Power IO Extender for UNIHIKER K10

Introduction 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. Specification Power Input: DC 5V via Type-C or MicroUSB Power Control: Main power switch and a red LED indicator Digital I/O Ports: 19x (3.3V Logic, functions consistent with UNIHIKER K10) Multi-functional Ports: 4x (C0-C3, 3.3V Logic, for Analog/Digital/Sensors) Servo Ports: 4x (S0-S3, 5V power from main input) I2C Ports: 3x total (2x 3.3V, 1x 5V dedicated for HuskyLens) Onboard Buzzer: Passive buzzer on Pin P0 with an enable/disable switch Dimensions: 66mm x 50mm x 12mm (L x W x H) Mounting Holes: 55mm spacing, 3.1mm diameter Shipping List IO Extender for UNIHIKER K10 x1

• Stable and Reliable Power for Robotics: Four dedicated servo ports (S0-S3) draw power directly from the 5V main input, bypassing the mainboard to deliver high-current, stable output. Eliminates jitter and instability when driving multiple servos or motors, ideal for robotic arms, walkers, and precision mechanisms.
• Simplified and Versatile Connectivity: All interfaces feature clear silk-screen labels for fast, error-free wiring. Four multi-function C-ports (C0–C3) support digital, analog, and common sensors like DHT11/22 and 18B20, speeding up environmental monitoring and data logging projects.
• Optimized for AI Vision Applications: Includes a 5V I²C port designed for HuskyLens, providing stable power even during high-load tasks like face or object recognition. Ensures reliable operation and reduces power-related failures in AI applications.
• Full micro:bit Ecosystem Compatibility: Compatible with micro:bit V1 and V2, featuring a built-in buzzer on P0 and a separate MicroUSB power port. Input spacing prevents simultaneous connection of Type-C and MicroUSB, improving safety in educational and collaborative settings.
