LTE communication module designed for stable and fast data transfer in IoT projects in Europe, Asia and Africa, supporting LTE-FDD B1/B3/B7/B8/B20/B28 bands. It communicates via UART and USB-C port, supports popular network protocols (TCP/UDP/HTTP/MQTT/HTTPS) and operates in low power mode - only 0.6 mA in sleep mode. Thanks to compatibility with 3.3V/5V logic systems, wide power supply range (5-12V) and wake-up function via UART, it is ideal for remote and energy-saving industrial applications. DFRobot TEL0177
