Raspberry Pi MHS & GPIO Display

TEST-RPI-EXP-01

Published

Compact touchscreen display demo page connected via GPIO header, suitable for device panels and prototype validation.(Standalone product 1)

Raspberry Pi GPIO Display Auxiliary View

Introduction

Direct header connection, reducing external adapter cables.
Integrated resistive touch area, suitable for menus and status operations.
Provides a maintainable unified product documentation structure.
Standalone product ID: 1.

Specifications

Specifications to be added.

Hardware

The module draws power and transmits display/touch signals via dual-row GPIO socket. Align with pin 1 during installation; avoid hot-plugging.

Size

关闭Development Board电源并核对排针方向.
Press the display module evenly onto the GPIO header.
Install the demo driver and select the corresponding rotation.
Perform touch calibration and save parameters.

FAQ

Is slow screen refresh normal?: SPI mode speed is affected by bus frequency and refresh area; partial refresh is preferred.
How to handle touch drift?: Recalibrate and check if the module is under mechanical stress.
