Zecko ES is a multifunctional embedded system built on the Unihiker K10, integrating features like photography, audio playback, fitness tracking, AI-based face recognition, and a reflex-based game. The system is developed entirely in C++, leveraging the Unihiker K10’s sensors and multimedia capabilities. A custom 3D-printed enclosure ensures full accessibility and optimal performance.

This project demonstrates the versatility of the Unihiker K10 in real-world applications and explores the integration of AI and embedded hardware in a single compact device.
STEP 1
Design the functionality and features of Zecko ES.
STEP 2
Develop the system in C++ on the Unihiker K10 using PlatformIO.
STEP 3
Create a 3D-printed enclosure for housing the board while maintaining access to sensors and GPIO pins.
STEP 4
Test and validate all modules: camera, music, workout, AI recognition, weather, and games.
Zecko ES leverages all major components of the Unihiker K10: the 2.8-inch color screen, camera, microphone, speaker, RGB light, accelerometer, light/temperature/humidity sensors, Wi-Fi, and Bluetooth connectivity. Each module of Zecko ES demonstrates a different use case for embedded systems:
Camera: Captures images and saves them to the SD card.
Music Player: Plays .wav files stored on SD card.
Workout Station: Tracks steps, sets, reps, and time.
Zecko AI: Chatbot that answers simple questions.
Weather Station: Displays temperature, humidity, light intensity, and noise levels.
AI Recognition: Detects faces using the camera.
Reaction Game: Reflex-based game where players respond to visual cues.
Journal: Records voice notes and saves them to the SD card.
Hardware Used:
Unihiker K10 – AI Coding Board
Flashforge Adventurer 5M – 3D printer for custom enclosure
ABS Filament – for enclosure printing

Testing & Validation:
Each module was individually tested:
Camera captures and stores images reliably.
Music player plays files from the SD card.
Workout tracking logs steps, sets, and reps.
AI recognition successfully detects faces.
Weather station accurately displays environmental data.
Reaction game and journal functions operate as expected.
This is a full presentation and showcase of the Unihiker K10 and its functionalities. Once again, I am grateful to have received the Unihiker K10 from DFRobot.
