Cutting-edge performance
ESP32-P4NRW32 MCU

The ESP32-P4NRW32 powers the latest Riverdi Embedded Display series, combining exceptional processing performance with advanced connectivity and multimedia features.

This high-performance MCU integrates a dual-core 32-bit RISC-V high-performance processor running up to 400 MHz, alongside a low-power RISC-V core operating up to 40 MHz for energy-efficient real-time and background tasks. Both cores feature instruction-set extensions optimized for digital signal processing, efficient graphics rendering, and lightweight AI inference at the edge.

The ESP32-P4 includes a Memory Protection Unit (MPU) and advanced security mechanisms, such as hardware encryption, secure boot, and trusted execution zones, ensuring strong system protection and data integrity.

It works with up to 64 MB of external Octal PSRAM and 64 MB of Octal Flash, providing high-speed memory access and ample storage capacity for demanding embedded and multimedia applications.

Featuring integrated Wi-Fi 6 and Bluetooth® 5.3 LE connectivity via its network radio subsystem, the ESP32-P4NRW32 delivers seamless wireless communication and flexible integration for modern connected devices.

With its powerful architecture, versatile interfaces, and secure design, it is the ideal choice for industrial, IoT, and HMI solutions requiring top-tier performance, responsiveness, and connectivity.

High brightness, IPS TFT

Typical surface luminance for a high brightness, IPS TFT displays is 800 up to 1000 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.

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.

Main features:

• ILITEK Touch IC-ILI2132A, with 10 years guaranteed availability
• USB/I²C interface
• Supports cover glass thickness up to 8 mm*
• Supports thick gloves operation (i.e. double gloves, tactical gloves)*
• Working with water on the surface
• Multi-touch, up to 10 points
• Great EMC, RS (radiated susceptibility) and CS (conductive susceptibility) performance

*Riverdi is skilled to adjust parameters up to specific needs (thicker gloves, thicker glass)

Optical / Air 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.

Customized displays

You can customize displays in many different 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.
