Description
STM32 Nucleo
The STM32 Nucleo boards from STMicroelectronics are affordable development platforms designed for quick prototyping and experimentation with any STM32 MCU. They feature standardized connectors for easy integration with a variety of hardware add-ons, such as Arduino Uno, Nano, and ST morpho connectors. These boards include a built-in ST-LINK debugger/programmer, eliminating the need for additional equipment.
High brightness, IPS TFT
Typical surface luminance for a high brightness, IPS TFT displays is 1200 cd/m² which means it is very bright even outdoors. The full viewing angles allow the user to interact with the display in a natural and intuitive way from every side. Please see the datasheet for more features.
TouchGFX support
Example demo board support package- “Swimming pool control” is available in TouchGFX designer.
Industrial Touch Screen
Reacts to the slightest touch
The PCAP (Projected Capacity touch panel) is classified as ‘industrial’ (as opposed to ‘consumer’) when it is able to operate correctly in more demanding, harsh conditions (i.e. disturbing electromagnetic fields around causing interferences with panel controller, water droplets present in the surrounding area also on panel glass), and react properly when touched by hands in gloves. It can be tuned at the factory, detect touch through thicker glass layers than consumer panels (6mm thick glass layer was tested with success in the Riverdi lab) and it uses an industrial grade chip controller. Such controllers have industrial manufacturer’s guidelines implemented and are guaranteed to be manufactured typically from 10 to 15 years without any changes.
Main features:
- ILITEK ILI2130 Touch IC
- I²C interface
- Supports glass thickness up to 6mm
- Operates with gloved hands
- Water-resistant touch functionality
- Multi-touch capability for up to 5 fingers
- Great EMC, RS (radiated susceptibility) and CS (conductive susceptibility) performance
- Touch performance could be easily tuned to fit specific needs

External memories
The STM32 Nucleo board features an onboard 8MB QSPI flash memory dedicated to handling assets efficiently. This external QSPI memory allows for faster data access and higher performance, supporting seamless storage and retrieval of pictures, music, video, fonts, and more. The board ensures high-speed data transfer and enhanced system capabilities through this integrated memory solution.
Optical Bonding
Enhancing the optical performance of your display
Optical bonding is a process of affixing the touch panel (or just the protective glass) to the display using a liquid adhesive, gel or dry (film). In general, this process improves the parameters of the module – the optical performance, as well as durability.
The air-gap is the reason for the phenomena of reflection of sunlight. So, when the display is off, the Visual Area (V.A) is never black – it is gray.
When removing the air gaps, we reduce the number of internal reflecting surfaces, which increase of optical performance. This phenomenon improves readability, by reducing the reflection and correct contrast.
Sleek design without any holes in the housing
A uxTouch display is a specially designed LCD TFT display which has a Projected Capacitive Touch (PTC). Thanks to their absolute flat design and multi-touch feature, they are the perfect choice for your project if you intend to have an interactive design and technology.
They feature a modern and sleek design without any holes in the housing.
On the technical side, they are a great option for industrial spaces since there is no dirt accumulation possible. They also feature chemically strengthened glass, which has increased durability, thanks to the process of ion-exchange. They are easy to assemble, easy to clean and easy to implement into your design.
Customized displays
The Riverdi Nucleo 3.5” Display Kit comes with a fixed standard High Brightness IPS Display.
You can customize those displays in many ways:
- Change the color, shape, and size of the cover glass
- Have your logo printed on the cover glass (or any other graphics you might need)
- Add a different interface
- Enhance the brightness of the screen
- Change the thickness of the cover lens for the CTP
- Choose a different viewing angle of the display
- Change the pinout
- Request different gasket assembly
As you can see the possibilities are endless. All you need to do is choose.
We will help you to get the perfect tailor-made product.
