4.3” Resistive GEMmodule™

Amulet Technologies MK-043R resistive 4.3” GEMmodule is a complete HMI system with a powerful application processor and graphical OS integrated into a touchscreen TFT display. Designed to simplify the development of graphical user interfaces (GUIs) for embedded systems, it provides a compact, ready-to-use solution for manufacturers and developers seeking to implement touch-enabled displays without requiring extensive hardware or software modifications. The module is suitable for a wide range of applications, including industrial control systems, medical devices, and consumer electronics, where intuitive human-machine interaction is important.

This module includes a 480 x 272 resolution WQVGA IPS TFT LCD that delivers clear, high-contrast visuals with wide viewing angles, enhanced by a white LED backlight. A resistive touchscreen interface enables accurate user input even in environments where gloves or styluses are used. The built-in application processor features a hardware floating-point unit, 24-bit color with alpha blending, a USB device interface, and multiple serial interfaces for connecting to the user's host microcontroller. On-board memory includes 64 Mb of SDR SDRAM to support smooth, high-resolution graphics, along with 32 Mb of serial data Flash for secure and reliable code storage. Built-in electrostatic discharge (ESD) protection helps increase system reliability in environments with high electrical noise.

A key feature of the GEMmodule is its use of the Amulet proprietary graphical operating system, which manages all GUI processing, including the handling of user events, independently of the user's host microcontroller. This enables developers to enhance existing systems, including those using 8-bit microcontrollers, without the need for major architectural changes. The OS is optimized for embedded use, offering reliable 24/7 operation, fast boot times, and a small memory footprint. The OS has built-in support for multi-language user interfaces, anti-aliased fonts, and native rendering of common image formats, such as animated GIF, JPEG, and PNG.

Development for the Amulet MK-043R resistive 4.3” GEMmodule is streamlined through full compatibility with Amulet’s GEMstudio™, a versatile GUI development environment designed to accelerate time to market. GEMstudio offers three flexible development approaches, including a full WYSIWYG drag-and-drop interface that requires no coding, making it accessible to users of varying skill levels. Applications can be created, tested, and deployed in a matter of days or weeks, significantly faster than traditional methods. Additionally, projects designed with GEMstudio can be easily migrated to the 4.3” GEMmodule or any other Amulet GEMmodule with minimal effort.
