The UNIHIKER K10 is a compact ESP32-based development board with an integrated LCD display, perfect for learning embedded systems and building interactive projects. This starter guide walks through the essentials: powering up the board, uploading firmware, and displaying text on the screen.

Following this guide, makers will receive a complete parts list, wiring diagram, step-by-step assembly instructions, and ready-to-use Arduino firmware that displays uptime on the LCD. The project demonstrates core concepts like screen initialization, canvas drawing, and timed updates—a foundation for more complex applications.

Assembly

2 steps

  1. Place the UNIHIKER K10 safely

    Set the UNIHIKER K10 on a non-conductive surface with its screen facing upward. Leave the built-in sensors and screen unobstructed.

    • Tip: Do not rest the board on loose metal objects or conductive foam.
    • ⚠ Avoid touching the board while it is powered if your hands are wet.

  2. Connect USB-C power and programming cable

    Connect a data-capable USB-C cable between the K10 and your computer. This project uses the board’s own USB power; no breadboard wiring or external components are required.

    • Tip: Use a USB data cable, not a charge-only cable.
    • Tip: Keep the cable connected while using Schematik’s Deploy button.
    • ⚠ Do not force the USB-C connector.
