The COM.LTE (4G) is an amazing stackable multifunctional LTE communication module. It comes with a built - in SIM7600G LTE communication module. This module supports various frequency bands including LTE - TDD, LTE - FDD, WCDMA, and GSM. It offers LTE.CAT4 with a 150Mbps downlink speed and supports voice calls and SMS. With stable performance, a small form factor, and high cost - effectiveness, it can transmit SMS and data with low power consumption. It has a DC power input and can get 5V - 12V power from an external supply. A DIP switch is used for easy pin configuration. The onboard microphone and 3.5mm headphone jack allow you to connect headphones with a microphone. Ideal for high - speed network scenarios like video calls, drone data transmission, and industrial IoT. By setting the DIP switch, its RXD/TXD can connect to M5Stack's UART. Remember to turn on the DIP switch on the audio configuration pin side during use. Key features include stackable design, support for voice calls, SMS, and cellular data, independent external power, built - in microphone, AT command control, MicroSIM card support, two LED status indicators, SMA external antenna, and UART 115200bps serial communication. It covers multiple frequency bands and offers different data transmission speeds. It's certified with CE, RCM, FCC, etc. The package includes a COM.LTE module and an SMA antenna. Suitable for remote meter reading, web spider SMS - notifiers, wireless communication, M2M industrial, vehicle - mounted, and video applications.
Using the M5Stack COM.LTE Module is easy. First, make sure you have an external power supply to provide 5V - 12V power to the module. When setting up the pins, use the DIP switch. You can connect the RXD/TXD of the module to M5Stack's UART by adjusting the DIP switch. For audio use, turn the DIP switch on the side of the audio configuration pin to ON. Insert a MicroSIM card into the module to enable communication. When making voice calls or sending SMS, the module will use the supported frequency bands. For data transmission, it will operate according to the available speeds like LTE Cat4. Keep the module in a dry and clean place. Avoid exposing it to extreme temperatures. If there are any issues with the SIM card, check the connection and ensure it's a valid card. If you face problems with the antenna, make sure it's properly connected to the SMA port. Periodically check the LED indicators to monitor the status of the module.
