Programmable IIoT Gateways | RS232, RS485, Wi-Fi, Ethernet, 2.4GHz

Break free from proprietary limits and build custom IIoT solutions without compromise. Tired of closed systems and lack of flexibility? Our Programmable IIoT Gateways are a game-changer in data acquisition and processing. Powered by high-performance ESP32 or industrial-grade STM32 microcontrollers, they give you full control over the device's logic. Implement custom protocols, perform edge computing, and send data exactly where you need it—without vendor lock-in. This isn't just a gateway. It's a Programmable Automation Controller (PAC) that becomes the heart of your system.

Take Control of Your Data – From Sensor to Cloud

Standard gateways just convert protocols. Our Programmable IIoT Gateways go a step further, combining the reliability of a PLC with the openness of a PC. This allows you to not only collect data from RS232 and RS485 devices but also to filter, aggregate, and analyze it in real-time, right on the device. You are in command of how your system operates.

The Power of Choice: ESP32 vs. STM32 Cores

We understand that every project is unique. That’s why we offer a choice between two industry-leading microcontroller platforms:

• ESP32-based Gateways: Perfect for rapid prototyping and applications where wireless connectivity is key. Leverage the power of a dual-core Xtensa® LX6 CPU, built-in Wi-Fi, and 2.4GHz band communication. Program in the familiar Arduino IDE or use the flexibility of MicroPython.

• STM32-based Gateways: Engineered for maximum reliability in critical industrial systems. Based on the proven ARM Cortex-M4 core, they guarantee stable and predictable performance. It's the ultimate choice for advanced real-time applications developed using FreeRTOS.

Key Advantages That Give You a Competitive Edge:

• Total Integration Freedom: You are not limited to Modbus or M-Bus. Implement any custom serial protocol and connect it to any cloud platform (AWS, Azure, Google Cloud) or a local MQTT broker.

• Powerful Edge Computing: Reduce transmission costs and latency. Execute complex logic, filter alarms, and aggregate data directly on the gateway, sending only relevant information to the cloud.

• Universal Connectivity Hub: Integrate RS232 and RS485 devices, connect to your network via Ethernet or Wi-Fi, and add wireless sensors using the 2.4GHz band—all in one compact device.

• Industrial-Grade Reliability: A wide operating temperature range (-40°C to +75°C), ESD protection for RS485 lines, DIN-rail mounting, and a 3-year warranty ensure dependable operation.

• No Hidden Costs or Vendor Lock-in: Forget about subscription fees. Our gateways are open platforms that you program using standard, free-to-use tools.
