Ebyte Multi-mode GNSS Positioning Wireless Modules with Modbus Protocol and Interface

Ebyte Multi-Mode GNSS Wireless Positioning Modules and Industrial Communication Devices with Modbus Protocol and Interfaces

Industrial Solutions for Multi-System Satellite Positioning and Serial Data Transmission in IoT Applications.

Ebyte multi-mode GNSS wireless positioning modules and industrial communication devices are designed for monitoring, telemetry, and IoT systems that require precise satellite positioning or serial data transmission to remote networks.

Depending on the model, the devices may integrate BDS, GPS, GLONASS, and GALILEO positioning systems, as well as industrial communication through RS232 or RS485 interfaces with Modbus RTU protocol. Some variants support GNSS data output in NMEA0183-compatible format, while others integrate 4G CAT1 connectivity for transparent transmission between serial devices and network servers.

Key Features

• Compatibility with multiple GNSS systems: BDS, GPS, GLONASS, and GALILEO (model dependent).
• Industrial communication via RS232 or RS485 interfaces.
• Modbus RTU protocol support for integration with PLCs and control systems.
• GNSS data output compatible with NMEA0183 format (variant dependent).
• Configurable communication speed up to 115200bps.
• GNSS update rate from 1Hz up to 25Hz (model dependent).
• Horizontal positioning accuracy up to 1.5m (model dependent).
• Wide DC power supply range for industrial environments.
• DIN rail installation with Phoenix-type terminal.
• Triple protection coating: anti-mold, moisture-resistant, and anti-salt spray.
• Compact design for integration into automation and IoT projects.
