The EBYTE ECM50 Series is an advanced, industrial-grade programmable Industrial Personal Computer (IPC) and Modbus gateway built around the powerful ESP32-S3 chip. Designed to handle full-scenario communication, this intelligent device bridges the gap between edge devices and the cloud. It seamlessly integrates a wide array of communication methods including 4G LTE, Wi-Fi, Bluetooth (BLE), Ethernet, and LoRa. With built-in support for MicroPython, developers can easily deploy custom business logic and edge computing tasks directly onto the gateway. Equipped with rich I/O ports (2DI, 2AI, 2DO) and industrial serial interfaces (RS485/RS232), the ECM50 is the ultimate solution for smart factories, agricultural IoT, smart city infrastructure, and automated assembly lines.
Core Features
-
MicroPython Programmable: Features an ESP32-S3R8 processor with 8MB PSRAM, allowing users to write and execute custom edge-computing scripts to significantly reduce server load and development time.
-
Unmatched Connectivity: Supports 4G LTE, Ethernet (RJ45), Wi-Fi, Bluetooth 5.0, and LoRa, ensuring reliable data transmission in both urban and remote environments.
-
Rich Industrial Interfaces: Comes equipped with 2 Digital Inputs (DI), 2 Analog Inputs (AI), 2 Digital Outputs (DO), alongside standard RS485 or RS232 serial ports for universal sensor and PLC compatibility.
-
Comprehensive Protocol Support: Natively supports Modbus RTU/TCP, MQTT, HTTP, and TCP/UDP, making cloud integration with platforms like AWS, Azure, or custom servers effortless.
-
Rugged Industrial Design: Built to withstand harsh environments with wide voltage input and isolated communication ports, ideal for outdoor testing, smart grids, and heavy industry.
Customer Use Cases
-
ECM50-A08EU: European Smart Manufacturing & Assembly Line Automation
-
Industry & Environment: Automotive parts manufacturing plant in Germany.
-
Usage: A factory manager needs to monitor the operational status of multiple PLCs and motor drives on an assembly line. They install the ECM50-A08EU gateway. Using its RS485 port, it easily daisy-chains to the existing Modbus RTU devices. The engineering team writes a custom MicroPython script to filter and average the data locally (edge computing) before pushing the critical alerts to an MQTT broker via the local Ethernet or the backup 4G (EU) network. The DO (Digital Output) ports are wired to a factory alarm beacon to instantly notify staff of any machine faults.

ECM50-A09LA: Remote Hydrology & Water Conservancy in Latin America
-
Industry & Environment: Remote reservoir and dam monitoring in Brazil.
-
Usage: Environmental engineers must monitor water levels and quality in a rural reservoir where Wi-Fi and Ethernet are unavailable. They deploy the ECM50-A09LA. The analog inputs (AI) are connected directly to water level sensors, while legacy testing instruments interface via RS232. Because it is the "LA" version, the device reliably connects to local Latin American 4G cell towers to transmit hydrological data to the cloud via HTTP/MQTT. If the water level exceeds a critical threshold, the onboard logic triggers a digital output (DO) to automatically close a specific valve, preventing overflow.

FAQ
Q1: Do I need to be an expert in C++ to program the ECM50 series?
A: Not at all. The ECM50 series is designed around the ESP32-S3 chip and natively supports MicroPython. This means you can write scripts in Python—a highly readable and beginner-friendly language—to handle data collection, protocol conversion, and custom edge-computing logic. EBYTE also provides rich official source code examples to help you get started quickly.
Q2: What is the main difference between the "EU" and "LA" versions?
A: The suffixes denote the regional compatibility of the built-in 4G LTE cellular module. The "EU" models are tuned for the LTE frequency bands primarily used in Europe, Asia, and Africa. The "LA" models are optimized for the frequency bands used in Latin America and parts of the Americas. Choosing the correct version ensures optimal cellular signal reception in your deployment country.
Q3: Can the ECM50 interface with legacy industrial equipment?
A: Yes. The gateway is available in both RS485 (A08 models) and RS232 (A09 models) configurations. It natively supports standard industrial protocols like Modbus RTU and Modbus TCP. Furthermore, it features 2 Analog Inputs and 2 Digital Inputs, allowing you to connect raw sensors directly to the gateway without needing an intermediary PLC.
Q4: How does the ECM50 connect to the cloud?
A: The ECM50 offers true full-scenario communication. You can connect it to the internet via the physical RJ45 Ethernet port, wirelessly via Wi-Fi, or remotely using the built-in 4G LTE modem. Once connected, it can push data to your custom servers or mainstream IoT cloud platforms (like AWS IoT, Azure, or AliCloud) using standard IT protocols such as MQTT, TCP, UDP, or HTTP.
Q5: Can I control physical hardware using this gateway?
A: Yes, the device features 2 Digital Output (DO) ports. Using your custom MicroPython scripts or remote cloud commands, you can toggle these outputs to trigger external relays, sound alarms, switch on pumps, or actuate valves, making it a complete control and monitoring node.
