Module connection and compatibility
The NB-IoT2 module communicates via UART at 115200 bps. It can be connected to compatible M5Stack systems, such as CoreS3 , using Grove ports . For the best signal quality, the included SMA antenna should be mounted.
NB-IoT 2 Applications
The NB-IoT2 module is ideal for IoT applications such as remote control and monitoring, asset tracking, telemedicine, smart meters, and urban bike sharing systems. With global compatibility with Cat-NB bands, it is a versatile solution for integration in projects requiring low energy consumption.
The module has an SMA connector for connecting the included antenna.
The module has compact dimensions of 71.5 x 24 x 8 mm.
Cat-NB: the perfect combination of low power consumption and wide range
Cat-NB (Category Narrowband) is a wireless communication technology developed specifically for IoT devices. It belongs to the NB-IoT (Narrowband IoT) standard within LTE and is designed for low-bandwidth data transmission with very low power consumption . Cat-NB offers reliable communication over long distances. With Cat-NB, IoT devices can efficiently transmit small data packets even in places with limited coverage.
In our offer you will also find other M5Stack modules.
