It is an LTE Cat-1 module that supports wireless communication modes such as LTE-TDD and LTE-FDD, and supports up to 10Mbps downlink rate and 5Mbps uplink rate. The module supports operating systems such as /Linux, supports multiple network protocols, and the module size is the same as the SIM7000/SIM7070/A7670E series. Most of the AT commands are compatible with the SIM800 series. It has strong compatibility and is suitable for IoT applications such as telematics, monitoring equipment, industrial routers, remote diagnosis, and satellite positioning. Based on the for 40PIN GPIO interface design, it is suitable for series motherboards. There are 3 additional USB expansion interfaces on board, which can expand the USB interface for host devices such as for and PC. Supports network communication protocols such as IP, HTTP(s), MQTT(s), (s) and , supports RNDIS, NDIS and dial-up Internet access, and supports GPS, GLONASS, , BeiDou (Beidou) positioning. Communication parameters: Supported frequency bands:LTE-FDD:B1, B2, B3, B4, B5, B7, B8, , B13, B18, B19, B20, B25, B26, B28, B66 LTE-TDD:B34, B38, B39, B40, B41 Data transmission:less than equal 5Mbps(UL), less than equal 10Mbps(DL) GNSS:GPS, GLONASS, , BeiDou Working parameters: Supply voltage:5V Logic level:3.3V Due to different batches, the printed words on the product be different, which does not affect use.
