P12 - Programmable IIoT Gateway on STM32 (Ethernet + 2x RS232 + 2x RS485)
P12 - Programmable IIoT Gateway on STM32 (Ethernet + 2x RS232 + 2x RS485)
- Hybrid Open IoT platform (STM32F4) with 2x RS232 and 2x RS485 ports, enabling the integration of diverse systems in a single device.
Product Description
The Redisage P12 is the most versatile model in the series of programmable controllers based on STM32. The device combines support for two serial communication standards, offering 2x RS232 ports and 2x RS485 ports. This allows for the management of mixed systems from a single application.
As an Open IoT platform, the P12 enables the creation of advanced control algorithms and data processing directly on the device. Key features:
• Hybrid Configuration: 2x RS232 + 2x RS485
• Processor: STM32F4 (Dual Core, high performance)
• Programmability: Fully open (C/C++, FreeRTOS)
• Power Supply: 12-30 VDC
• Application: Protocol conversion, Edge AI, process control

About P12
P12 – Versatile System Integration
The P12 Open IoT Gateway is a flexible development platform designed to handle heterogeneous industrial environments. The device eliminates the need for using different types of controllers by offering 2 RS232 ports and 2 RS485 ports in a single housing. This allows a programmer to handle, for example, local operator panels (HMI via RS232) and a distributed sensor network (Modbus RTU via RS485) within a single application on the STM32F4 microcontroller.
Thanks to full programmability (C/C++, FreeRTOS), the P12 can act as an advanced data concentrator, protocol converter, or standalone PLC. The Ethernet port provides connectivity to the cloud, MES/ERP systems, or other controllers on the factory network. The device is resistant to harsh operating conditions (temperature, electromagnetic interference), making it an ideal solution for "retrofitting" applications – modernizing older machinery.
The compact 2U DIN-rail housing allows for easy installation in control cabinets with limited space.
Technical Specifications:- Processor: STM32F4 (ARM Cortex-M4).
- I/O Ports: 2x RS232 (Tx/Rx) + 2x RS485 (A/B) + Ethernet.
- Openness: No vendor lock-in, full hardware access.
- Connectors: Screw terminals for all serial interfaces.
The P12 is a universal "Swiss Army knife" for embedded systems programmers in the industry. Full documentation and code examples are available on the support page.
