DFRobot UNIHIKER K10 Multi-Function Expansion Board

The integrated 18650 battery holder and charging/discharging circuit eliminates the need for cables and external batteries, while the onboard battery indicator light ensures safe power supply, convenient charging, and long battery life, greatly improving project mobility.

To overcome the pin limitations of the UNIHIKER K10, this expansion board provides a wealth of additional interfaces that pass through the UNIHIKER's native edge connector. It adds six multi-function I/O pins (supporting Digital, Analog, and 1-Wire), multiple I²C ports (including one 5V port for logic-level compatibility with devices like HUSKYLENS), and a dedicated 5V port for ultrasonic sensors. Furthermore, integrated peripherals such as two programmable RGB LEDs and an IR transmitter/receiver add built-in functionality for status indication and remote control without requiring extra modules.

Engineered for creativity and rapid prototyping, the expansion board features M3 mounting holes spaced to be perfectly compatible with LEGO^® Technic dimensions. This design allows for seamless and sturdy integration into custom mechanical structures, robotics chassis, and educational models. It bridges the gap between electronics and mechanical construction, enabling the creation of sophisticated, custom-built robots and devices.
