EC 20 – 4G LTE TTL Modem

The TTL interface, as mentioned earlier, is a standard serial communication interface. In the case of the EC20 module, it uses the UART protocol to establish communication with a host device. The TTL interface operates at logic levels, typically at 3.3V or 5V, and allows for data exchange through RX (receive) and TX (transmit) lines.

By utilizing the EC20 module with a TTL interface, developers can integrate 4G LTE connectivity into their devices and establish a communication channel with the cellular network. The TTL interface simplifies the integration process, enabling straightforward serial communication between the module and the host device.

Features of EC 20 – 4G LTE TTL Modem

• 4G LTE Connectivity: The EC20 module supports 4G LTE Cat-3 technology, providing high-speed wireless connectivity with download speeds of up to 100 Mbps and upload speeds of up to 50 Mbps. It allows devices to access the internet and transmit data over cellular networks.
• Backward Compatibility: In addition to 4G LTE, the EC20 module is also backward compatible with 3G (UMTS) and 2G (GSM) networks. This ensures that the module can operate in areas where 4G coverage may not be available.
• Global Frequency Bands: The EC20 module supports a wide range of global frequency bands, making it suitable for deployment in various regions worldwide. It allows for global roaming capabilities and compatibility with different cellular network operators.
• TTL (UART) Interface: The EC20 module features a TTL (UART) interface for communication with a host device. This interface uses RX (receive) and TX (transmit) lines to exchange data between the module and the host device. The TTL interface simplifies integration and communication with the module.
• GNSS Positioning: The EC20 module includes built-in GNSS (Global Navigation Satellite System) support, which enables devices to obtain accurate positioning information using satellite signals. This feature is useful for location-based applications or tracking devices.
• Compact Form Factor: The EC20 module is designed with a compact form factor, making it suitable for integration into space-constrained devices and applications. Its small size allows for flexible and convenient installation.
• Power Management: The module incorporates power-saving features to optimize power consumption and extend the device’s battery life. It supports various power modes, such as idle mode and sleep mode, to conserve energy when the module is not actively transmitting or receiving data.
