Modules

This Crowtail series 4G module is a high-performance LTE Cat1 wireless module. It uses the SIM A7670E communication module from Simcom and communicates through a UART interface, which enables 4G data transmission and voice communication. The module supports multiple LTE bands, including B1/B3/B5/B7/B8/B20, as well as WCDMA and GSM networks. In addition, it supports various protocols such as TCP/IP, FTP, HTTP, and multiple satellite navigation systems such as GPS, GLONASS, and BDS. The module comes with a charging interface and can be powered by a 3.7 V lithium battery or a 5 V USB-C interface. It also has a 3.5 mm headphone jack, and by connecting a headphone with a microphone, it can be used for making and receiving phone calls. Its compact size makes it easy to integrate into various IoT devices and meet various application requirements. Furthermore, its low power consumption and reliable performance are also the reasons why it is widely used in IoT, smart home, automotive, and industrial control fields.
