Overview
This molecule integrates a 7-inch Luckfox touchscreen display with a built-in Raspberry Pi single-board computer. The display supports 1024×600 resolution with capacitive touch input, while the embedded Raspberry Pi provides full computing capabilities including HDMI output, USB ports, Wi-Fi, and GPIO access. All power, video, touch, and GPIO signals are broken out to machine contacts around the molecule’s perimeter.

- xrp platform
NSF Relevance
This molecule allows users to prototype and test display-driven applications directly on the embedded Raspberry Pi. For example, a student adding an Edge AI camera to their XRP robot can use the display to view live video from the camera and test object detection algorithms in real time. It also supports experimentation with different camera sensors, GUI development, and interactive projects.
Integration Guide
To use 7in Display Molecule in your design:
- Download the schematic symbol and PCB footprint from the Files section
- Import into your EDA tool (KiCad or Fusion 360 / EAGLE)
- Place the molecule in your schematic and connect the interface pins
- Use the 3D model (.glb) for mechanical fit verification
