SIM7600CE 4G LTE Module RS232 USB Multi-Network Cellular Connectivity

This SIM7600CE 4G LTE module provides reliable cellular communication across a wide range of network standards, including TDD-LTE, FDD-LTE, TD-SCDMA, UMTS, HSPA+, CDMA, EVDO, GSM, GPRS, and EDGE. Controlled by standard AT commands via RS232 or USB interface, it integrates easily into IoT, M2M, and embedded systems. Its compact 30 x 30 x 2.9 mm size suits space-constrained designs, and the wide operating temperature range of -40°C to +85°C ensures performance in harsh environments. The white module requires a 3.4V to 4.2V supply.

Features and Construction

Designed for flexible deployment, the module covers multiple frequency bands and network generations. Its AT-command control simplifies firmware development, and the dual-interface connectivity reduces wiring complexity.

Network and Band Support

The module supports TDD-LTE bands B38/B39/B40/B41, FDD-LTE bands B1/B3/B8, TD-SCDMA B34/B39, UMTS/HSDPA/HSPA+ B1/B8, CDMA 1X/EVDO BC0, and GSM/GPRS/EDGE 900/1800 MHz. This all-netcom capability allows use across different carriers and regions without hardware changes.

Electrical and Thermal Specifications

Operating voltage is 3.4V to 4.2V, making it compatible with standard 3.7V Li-ion battery supplies. The temperature range of -40°C to +85°C suits outdoor or industrial installations where ambient conditions vary widely.

Mechanical Dimensions

The module measures 30 x 30 x 2.9 mm, offering a small footprint for integration into PCBs or enclosures. The white colour aids visual identification during assembly.

Uses and Placement

This module is intended for developers and engineers adding cellular connectivity to devices such as remote sensors, vehicle trackers, data loggers, or portable terminals. Its multi-band fallback ensures stable communication even when 4G coverage is unavailable.

Professional and Industrial Use

In industrial automation, the module can transmit sensor data over cellular networks. The wide temperature tolerance and ruggedised components make it suitable for factory floors, cold storage, and outdoor cabinets.

Prototyping and Integration

The RS232+USB interface simplifies breadboard testing and firmware prototyping. Developers can send AT commands directly from a PC terminal to validate functionality before embedding the module into a custom design.

Benefits and Buying Value

This module reduces development effort by supporting multiple network technologies in one compact unit. Its all-netcom compatibility avoids the need for region-specific variants, cutting inventory complexity.

Reliable Connectivity

Automatic fallback from LTE to 3G, CDMA, or GSM ensures data transmission continues during network transitions. The module handles switching without user intervention, maintaining uptime for critical applications.

Ease of Use

Standard AT commands are well-documented and widely used, so existing codebases require minimal adaptation. The dual-interface approach gives flexibility in choosing a communication bus based on system architecture.
