CTA base — Embedded CPU for professional systems

In a fast and competitive market, companies and development teams need reliable, ready-to-use solutions to reduce design time and accelerate time-to-market. Our CTA base embedded platform was created precisely with this goal in mind: to offer a robust, versatile technological foundation already integrated with everything you need to build modern and scalable electronic applications.

Computing power and memory for complex applications

At the heart of the board is an STM32F769 microcontroller (ARM Cortex-M7), capable of reaching 216 MHz. This architecture delivers high performance even in applications requiring intensive processing, such as smooth graphical interfaces, multiple communication protocols, and real-time peripheral management.

• 1 MB internal RAM and 8 MB external SDRAM allow you to handle complex applications without compromise.
• 2 MB internal Flash and 16 MB external QSPI Flash provide ample space for firmware, data, and media assets.

Integrated connectivity for IoT and industry

Today, no platform can be considered complete without advanced connectivity. This board integrates:

• Wi‑Fi and Bluetooth for IoT applications and wireless communications.
• 100 Mbps Ethernet for stable and fast wired connections.
• Modbus over RS‑485 for industrial environments.
• MDB vending for interfacing with payment systems in commercial applications.
• CAN bus for interacting with devices and sensors in automotive or automation contexts.

This way, the board is ready to communicate with machines, sensors, cloud systems, and mobile applications.

Display and graphical interface

One of the strengths of the platform is the 7” TFT display with high resolution (800x480 px) and RGB888 support, perfect for modern and intuitive HMI interfaces. The resistive touchscreen enables simple and direct interaction, ideal for industrial, vending, and machine control applications. Thanks to the power of the Cortex‑M7 and FreeRTOS support, you can build responsive, customized graphical interfaces without external hardware.

Expandability and flexibility

Every project has different needs. For this reason, the platform offers an expansion connector with:

• UART, I²C, SPI, and CAN
• GPIO dedicated to both the STM32F769 microcontroller and the ESP‑WROOM‑32 module

This flexibility makes it easy to integrate sensors, actuators, or custom modules, turning the board into a tailored solution for your project.

Integrated software

Beyond hardware, the board already includes a ready-to-use software environment:

• FreeRTOS as a real-time operating system for efficient task management.
• Built-in diagnostic menu, useful for testing and maintenance.
• OTA (Over-The-Air) updates, allowing you to update firmware remotely without physical intervention.
• Local and remote operation logs for continuous monitoring and preventive diagnostics.

Industrial robustness

The board is designed to withstand real-world conditions:

• 24V AC/DC power supply compatible with industrial systems.
• Low power consumption (250 mA @ 24V DC) to reduce energy costs.
• Panel mount and compact dimensions (110 x 195 x 35 mm) for easy integration.
• Reliable components, including backup battery and buzzer for audible notifications.

One platform, endless applications

The versatility of this board makes it suitable for various sectors:

• Industrial automation: machine control, process supervision, data collection.
• Vending and retail: management of vending machines with integrated MDB protocol.
• IoT and smart devices: wireless and wired connectivity for smart systems.
• HMI and user interfaces: integrated touch display for modern, customizable control panels.
• Rapid prototyping: a ready base to test new ideas without starting from scratch.
