Module NBIoT

SKU:M028

Description

Module NBIoT is an NB-IoT communication module in the M5Stack stackable module series. It integrates a high-performance NB-IoT full-network wireless communication module M5311. The low-power design helps customers achieve longer terminal life. The M5311 provides rich external interfaces and protocol stacks, supports external sensor devices, and offers great convenience for user product development. It also supports the OneNET cloud platform protocol, enabling seamless integration and rapid development. This module is particularly suitable for IoT industries such as smart metering, smart wearables, smart parking, and municipal management, where ultra-low power consumption and ultra-small size are core requirements.
