Introduction
- Expansion board form factor for direct stacking on common controller boards.
- Suitable for dashboards, menus, and sensor data display.
- Example parameters and steps maintainable via admin form.
- Standalone product ID: 2.
Specifications
Specifications to be added.
Hardware
The expansion board routes display bus, touch signals, and SD card interface to standard headers. Confirm controller board logic level before use.
Size
- Align the expansion board with the controller board header.
- Install the matching display driver library.
- Run color and touch test examples.
- Adjust pin definitions and UI per project requirements.
FAQ
- What if compilation shows insufficient capacity?
- Reduce font and bitmap resources, or choose a controller with more capacity.
- What if colors are abnormal?
- Check driver model, color order, and initialization orientation settings.
