COM.LTE(4G)

SKU:M031-A

Description

COM.LTE(4G) is a stackable multifunctional LTE communication module, built-in LTE communication module SIM7600G, supports LTE-TDD/LTE-FDD/WCDMA and GSM frequency bands, supports LTE.CAT4 (downlink speed is 150Mbps), supports voice calls SMS with SMS.

It has stable performance, small appearance, high cost performance, and can realize the transmission of SMS and data information with low power consumption. The module has a DC power input and can provide 5V-12V power supply through an external power supply.

In order to facilitate the user to configure the pin, the DIP switch is used to set the pin. The onboard microphone and 3.5mm headphone jack support the insertion of headphone with microphone. This module is especially suitable for scenarios that require high-speed network connections, such as video calls, drone data transmission, industrial Internet of Things, etc.

Notice

When used with the FIRE main control, due to the PSRAM pin conflict, please switch the DIP switch pins of the module base to TX(0/13), RX(5/15), and the device can use USB/ External DC is used for power supply.
When used with Core2 series main control, due to the different order of the base pin array, COM.X base pins TX(16), RX(17) correspond to the actual pins TX(14), RX of the Core2 main control (13) The equipment needs to use external DC for power supply.
