P11 - Programmable IIoT Gateway on STM32 (Ethernet + 4x RS485)
P11 - Programmable IIoT Gateway on STM32 (Ethernet + 4x RS485)
- Open hardware platform (STM32F4) with 4 independent RS485 ports, dedicated to managing extensive sensor and meter networks.
Product Description
The Redisage P11 is a programmable hardware platform dedicated to managing industrial RS485 buses. Based on the STM32F4 processor, it offers 4 independent RS485 ports, allowing for parallel handling of multiple subnets (e.g., Modbus RTU, BACnet MSTP).
As an Open IoT device, the P11 gives developers full freedom to implement control logic and data processing. Key features:
• High I/O Density: 4x RS485 in a 2U module
• Performance: ARM Cortex-M4 Microcontroller (STM32)
• Programmability: C/C++, FreeRTOS
• Power Supply: 12-30 VDC
• Protection: ESD protection on RS485 lines

About P11
P11 – Programmable RS485 Control
The P11 Open IoT Gateway is a solution dedicated to BMS and automation developers who need a flexible tool to handle multiple RS485 buses. Unlike standard gateways, the P11 is an open PAC controller based on the STM32F4 microcontroller, which enables the implementation of custom communication protocols (e.g., non-standard frames, custom polling logic).
The device features 4 RS485 ports, allowing for physical segmentation of sensor or meter networks. This enables the programmer to distribute the communication load across four independent channels, increasing system responsiveness. Each port supports 120 Ohm termination (manually enabled), which is crucial for signal integrity on long lines.
The P11 is equipped with an Ethernet port, allowing easy integration with IT systems (e.g., sending data to an SQL database, MQTT broker, or HTTP server). Robust construction and ESD protection make it an ideal hardware platform for custom industrial applications.
Technical Specifications:- Processor: 32-bit ARM Cortex-M4 (STM32F4).
- Interfaces: 4x RS485 (Terminal block A, B) + Ethernet.
- Environment: Any STM32 compatible (e.g., C/C++, FreeRTOS).
- Enclosure: Compact 2U DIN-rail mount.
The P11 is the choice for professionals who want full control over code and hardware. Technical documentation and SDKs are available on our manufacturer's portal.
