Building a Custom Android HMI Panel with PX30 SBC and 10.1’’

📘 Building a Custom Android HMI Panel with PX30 SBC and 10.1” TFT Display

This project demonstrates how to create a custom Android-based HMI panel using a Rockchip PX30 SBC and a 10.1” industrial TFT display.

📝 Project Overview

This project showcases how to build a custom HMI (Human-Machine Interface) panel using a Rockchip PX30-based Android SBC and a 10.1” LVDS TFT LCD (model: RK101HI34E). The final device supports Wi-Fi, capacitive touch, high-brightness display, and Android GUI — making it ideal for smart homes, industrial equipment, and control terminals.

The 10.1” RK101HI34E TFT display used in this project belongs to a series of industrial-grade modules designed for embedded applications requiring long life, high brightness, and stable touch performance.
