Description
High performance
STM32 MCU
STM32 Embedded Display series from Riverdi are currently, the highest resolution (1280×800 pixel) displays with STM32H757XIH6 on the market.
Dual core: it combines high-performance Arm® Cortex®-M7 and Cortex®-M4 32-bit RISC cores. The Cortex®-M7 core operates at up to 480 MHz and the Cortex®-M4 core at up to 240 MHz. Both cores feature a floating-point unit (FPU) which supports Arm® single- and double-precision (Cortex®-M7 core) operations and conversions (IEEE 754 compliant), including a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.
It features a 2 Mb flash memory that can be used for storing programs and data.
High RAM size: 1 Mb
Multi-Interfaces
RS232
RS485
Expansion connector
The board offers additional and independent GPIOs over a 40pin, 1.27mm male header. It provides direct access to the below GPIOs of MCU STM32H757XIH6, that makes it possible to be easily extended by an addon board for specific application.
List of interfaces on Expansion connector:
- 2 x I2C
- 1 x UART
- 1 x USART
- 1 x SPI
- 1 x USB
- 7 x PWMs
- 2 x DACs (Digital-to-analog)
- 2 x ADCs (Analog-to-digital)
Fully independent 2xCAN FDs
Applicable in industrial and automotive area.
USB
Can be configured to both Host and Device.
Fast-programming SWD port
SWD connector allows to program STM32 and QSPI with customer’s applications. Riverdi developed the ST-LINK programming cable that is included in the STM32 Embedded Display sample package (single packing).
Haptic feedback driver output
A DRV2605L haptic driver on the board (on I2C1) can be used to drive ERM and LRA haptic motors. Enhances feedback and conveys useful information to the users.
RiBUS
In some applications there might be a need to connect a second display in one device. With the STM32 Embedded Display line it is very easy as these displays are equipped with Master RiBUS connector – universal interface to Riverdi’s intelligent displays. In this way, the second display does nots need an external host controller and 2 independent displays can be controlled by one STM32.

External memories
64Mb External SDRAM with 32-bit data bus
The synchronous SDRAMs achieve high-speed data transfer using pipeline architecture.
32-bit wide access:
- Enables faster access to data
- Higher refresh rate – higher resolution and animations.
512Mb External QSPI
The board is equipped with a separate 512Mb flash memory. It can store pictures, music, video, fonts, etc. QSPI can be accessed over the SWD interface on the board with any official ST programmer.
Micro-SD card slot
Additional external storage. Supports uSD card type: SD, SDHC and SDXC cards.
TouchGFX support
Example demo board support package- “Smart home” is available in TouchGFX designer.
Wide input supply range
Power supply voltage ranges from 6.0 V- 48.0V. A wide power supply comes with a wide range of application. Reverse polarity protection which ensures the device is not damaged if the power supply polarity is reversed. The module also can be powered from interface connectors: RS232, RS485, 2xCAN FDs. They are internally connected.
Plug & Play PoE Addon (separate accessory)
PoE stands for Power over Ethernet and refers to the ability to use an Ethernet cord to carry network data and electrical power to connected devices. The 2 x 20-pin, 1.27 mm, pin sockets, are used to connect the Riverdi PoE Add-on Board. The Riverdi PoE Add-on Board features a 10/100M Ethernet Port with Power-Over-Ethernet enabled. It allows you to power the module through the Ethernet port.
Low EMI design
STM32 Embedded boards were designed with special attention paid to electromagnetic compatibility, a design that has given them a high immunity to external electromagnetic signals which otherwise could have disturbing influence on their working correctly.
Board is equipped with low noise backlight converters thanks to which they produce low electromagnetic interference (EMI) to the surrounding space. In consequence, external electronic devices or circuits do not need special electromagnetic screening.
The EMC measurements held in a specialized laboratory confirmed low electromagnetic emissions of STM32 Embedded modules, even when displaying dynamic pictures.
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.
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.
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 Touch IC-ILI2132A, with 10 years guaranteed availability
- USB/I²C interface/Optional UART
- Supports cover glass thickness up to 15mm
- Supports double gloves operation – not only nitrile –even double thicker gloves
- Working with water on the surface
- Multi-touch, up to 5 fingers
- Great EMC, RS (radiated susceptibility) and CS (conductive susceptibility) performance
- Touch performance could be easily tuned to fit specific needs

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.
