Quectel EC200U-CN 4G TTL Modem – GPS/GNSS Version

Product Description

The Quectel EC200U-CN TTL Modem (GPS Edition) is a versatile cellular communication module combining 4G LTE Cat 1 connectivity with integrated GPS/GNSS positioning. It is designed for IoT applications that require both reliable cellular communication and real-time location tracking.

Based on the EC200UCNAA-N05-SGNSA module, it is suitable for vehicle tracking, asset monitoring, fleet management, logistics, industrial equipment, and remote telemetry.

Integrated 4G & GPS/GNSS

Unlike the standard EC200U-CN version, this model supports GNSS/GPS, allowing applications to obtain location information such as latitude and longitude while simultaneously using the cellular network for data communication.

The module supports 4G LTE-FDD, LTE-TDD, and GSM networks and is designed for use with major Indian cellular networks, including JIO and Airtel, according to the supplied product information.

High-Speed LTE Cat 1 Connectivity

The module supports LTE Cat 1 data communication with a stated maximum speed of approximately 10 Mbps download and 5 Mbps upload, making it suitable for transmitting tracking information, sensor data, telemetry, and other IoT information.

Developer-Friendly 5V Design

The board includes an onboard TTL level converter and is designed for 5V power operation, making it convenient for development with Arduino and other compatible microcontrollers.

It provides both TTL UART and Micro USB interfaces, allowing the module to be connected directly to a microcontroller or computer for testing, configuration, and AT command communication.

Dual Communication Interface

TTL UART

The TTL serial interface allows direct communication with Arduino, ESP32, STM32, and other compatible microcontrollers.

Micro USB

The Micro USB interface can be used for PC communication, testing, configuration, and modem development. The supplied information also specifies switchable USB/TTL communication.

Improved Thermal Design

The module uses a laser-carved metal-style construction designed to provide improved durability and heat dissipation. This helps support stable operation during continuous cellular data transmission.

Technical Specifications

Working Principle

The modem connects to a supported cellular network using a compatible Micro SIM card and 4G antenna. A controller or computer communicates with the modem through the UART or USB interface using AT commands.

The integrated GNSS receiver can obtain positioning information from satellite signals, while the cellular connection can transmit the collected location and sensor data to a remote server or cloud platform.

Communication Protocols

The module supports common cellular and IoT communication methods, including:

• TCP
• UDP
• MQTT
• HTTP
• Standard AT commands

These interfaces allow the modem to be integrated into remote monitoring, telemetry, tracking, and cloud-connected applications.

Important Note

SIM Card

A compatible Micro SIM card with an active cellular data service is required for network connectivity.

Antennas

A suitable 4G cellular antenna and GPS/GNSS antenna should be connected to their respective ports for reliable operation.

Power Supply

Cellular modules can draw significant current during network transmission. Use a stable 5V supply capable of meeting the module’s current requirements, with up to approximately 2A recommended according to the supplied information.

GPS/GNSS Availability

GPS/GNSS positioning depends on satellite visibility, antenna placement, environmental conditions, and signal reception. Indoor or obstructed environments may reduce positioning performance.
