Module NB-IoT Plus

SKU:M030

Description

The Module NB-IoT Plus is an NB-IoT communication module in the M5Stack stackable module series. It integrates a high-performance NB-IoT wireless communication module M5311 - GB (International Version), which supports more frequency bands compared to the M5311-LV, including B1/B3/B5/B8/B20/B28. The module comes with a built-in copper spiral antenna and also provides an ipex connector for users to connect an external antenna for better signal strength. The module supports sleep mode and is designed with low power consumption, which helps extend the terminal's lifespan. The M5311-GB offers rich external interfaces and protocol stacks, supporting external sensor devices, making it highly convenient for product development. This module is particularly suitable for industries such as smart metering, smart wearables, smart parking, and municipal management, where ultra-low power consumption and compact size are critical requirements.
