## Description

DescriptionThis is a wireless communication module, integrated an NB-IoT M5311 module that produced by China Mobile. The dimension if M5311 is 16mm * 18mm*2.2mm, which is very tiny, and gives convenience to the user of more flexible dimension requirement.package with LCC allows quick production through standard SMT, which provides a more reliable connection method and performance on the extreme environment. the power requirement of this M5311 module is down to 2.1V, AA battery supported, it can fully utilize the power of AA battery, to provide an extremely low-power-consumption solution for terminal devices. M5311 provides abundant external interfaces and protocol stacks, support peripheral sensors, etc. Based on M5311, we have offered extra hardware resources on NB-IoT Module, WUP, STA LEDs, 3 alternative UARTs, one power button, and 2 alternative antennae. 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 Product Features Serial communication: UART Product Power in : 5V 3x Alternative UARTs 2x antenna: Spring / External WUP, STA LEDs 1x Power Button Nano SIM(Exclude SIM card) M5311 Package: LCC Frequency Band: B3/B8/B5 Tem:-40°C ~ 85°C NB-IoT support LTE Cat NB2* LTE Cat NB1 speed (kbps): Single Tone:15.625(UL)/21.25(DL) Multi Tone:62.5(UL)/21.25(DL) SMS: PDU/TEXT mode Network Protocol: IPv4/IPv6/UDP/TCP/ CoAP/LwM2M/HTTP/MQTT/TLS power in: 2.1V ~ 3.6V,Typ 3.3V (Low-Voltage version) & 3.0V ~ 3.6V,Typ 3.3V (Fixed-Voltage version) Interface： USIM ×1(1.8V/3.0V) UART ×2 I2C ×1 SPI ×1 RESET ×1 GPIO ×2 ADC ×1(10bits) 2x Antenna Consumption: 3uA@PSM 0.4mA@ldle mode(DRx=1.28S) 167mA@Tx(23dBm/15kHzST) 54mA@Rx -output power: 23dBm±2dB Certificate: CCC/SRRC/NAL/GTI Include1x NB-IoT module Application Smart Wearable device Smart Parking Smart Meter IoT in City
