## Description

## Overview

The DFRobot UNIHIKER K10 is an all-in-one AI coding board designed for K-12 STEM education, built around the ESP32-S3 with a 2.8-inch color LCD touchscreen (240x320). It packs an impressive array of onboard sensors and peripherals including a 2MP camera, microphone, speaker, RGB LED, and environmental sensors for temperature, humidity, light, and acceleration — all in a compact 51.6 x 83mm form factor.

What sets the K10 apart is its pre-loaded suite of AI models that work offline: face detection, pet recognition (cat/dog), QR code scanning, motion detection, and local speech recognition with custom voice commands. Students can also train their own TinyML models using camera or sensor data, making it a hands-on platform for learning computer vision, voice AI, and machine learning concepts without cloud dependencies.

Programming is done through MicroPython or the graphical Mind+ drag-and-drop environment, making it accessible to beginners while still powerful enough for intermediate projects. With WiFi 2.4G and Bluetooth 5.0 connectivity, Gravity 3/4-pin expansion connectors, edge connectors, a microSD card slot, and a PH2.0 battery port, the K10 supports IoT projects, sensor data logging, and wireless communication experiments alongside its AI capabilities.
