NB-IoT Plus is a wireless communication module, integrated with the NB-IoT M5311-GB module from China Mobile. It supports multiple frequency bands such as B1 / B3 / B5 / B8 / B20 / B28. It's very tiny form factor gives more convenience for applications with flexible dimension requirement. It comes with a built-in copper helical antenna, and also an IPEX connector, reserved for adding an external antenna to obtain better signal strength.Package with LCC allows quick production through standard SMT, which provides a more reliable connection method and performance in extreme environments.The power requirement of this M5311-GB module is as low as 2.1V,it supports and can fully utilize the power of AA battery, to provide an extremely low-power-consumption solution for field deployed terminal devices.M5311 provides abundant external interfaces and protocol stacks, and also support for peripheral sensors, etc.Based on M5311-GB, we have offered extra hardware resources to the NB-IoT Module, WUP and STA LEDs, 3 alternative UARTs, a power button, and support for two alternative antennae.
This product is EOL now, we've released the updated version COM.NB-IoT Module(SIM7020G) which is fully compatible with this product.
More info about NB-IoT: NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage. Battery life of more than 10 years can be supported for a wide range of use cases.Supported by all major mobile equipment, chipset and module manufacturers, NB-IoT can co-exist with 2G, 3G, and 4G mobile networks. It also benefits from all the security and privacy features of mobile networks, such as support for user identity confidentiality, entity authentication, confidentiality, data integrity, and mobile equipment identification. NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow-band of 200kHz. It uses OFDM modulation for downlink communication and SC-FDMA for uplink communications
M5Stack Fire has occupied GPIO16 / 17 to connect with the PSRAM by default, it's conflict with TXD / RXD (GPIO16, GPIO17) of NB-IoT Plus module. Therefore, when using the NB-IoT Plus module with the M5Stack Fire, you might have to cut the TXD and RXD from NB-IoT Plus module and wire fly to another set of UART pin
This product is EOL now.
