DevelBoard HMI

Control board for TFT capacitive displays, based on embedded Linux and Cortex A5 architecture

DevelBoard HMI

The DevelBoard HMI card is usually supplied as a complement to the Qt GUI design activity and based on an Embedded Linux system with Cortex A5 architecture.

The DevelBoard can be supplied with a 4.3″ or 7″ capacitive touch display. Thanks to a modular assembly the DevelBoard is available in different configurations according to the needs of physical interfacing with the outside (USB, ethernet, WiFi, serial, ADC, PWM, etc.).

It is a product for industrial low consumption and low cost applications. The typical use of the DevelBoard HMI is in the field of human-machine interfaces for numerical control systems. The DevelBoard HMI is also for domotics applications, such as remote management and control systems.

Designed for industrial and home automation

Based on our knowledge and experience in the embedded industry.

Wide range of customization

It is possible to provide DevelBoard HMI with all common interfaces and protocols.

Perfect for Qt framework based user interfaces

Thanks to the partnership with The Qt Company, compatibility is ensured.

Comprehensive solution

The guarantee of a complete hardware and software solution from a single supplier.
