NB-IoT Shield

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.

New physical layer signals and channels are designed to meet the demanding requirement of extended coverage – rural and deep indoors – and ultra-low device complexity. Initial cost of the NB-IoT modules is expected to be comparable to GSM/GPRS. The underlying technology is however much simpler than today’s GSM/GPRS and its cost is expected to decrease rapidly as demand increases.

 

Arduino is an open-source electronics platform based on easy-to-use hardware and software, it is an easy tool for fast prototyping, aimed at students without a background in electronics and programming. As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT applications, wearable, 3D printing, and embedded environments. All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs. The software, too, is open-source, and it is growing through the contributions of users worldwide.

 

NB-IoT Shield is an expansion board for Arduino to add NB-IoT technology. With NB-IoT Shield and Arduino, user can study/evaluate and do POC for NB-IoT solution rapidly.

 

The NB-IoT Shield is loaded with offshore NB-IoT module. include:

  • Nb-IoT Bee QB05, QB08, QB20, they use Quectel BC95-B5 /B8 and B20 module. The module is designed for only use in NB-IoT network. and difference suffix reference to different NB-IoT Band. (These modules are discontinue. recommend to use NB-IoT Bee 95G as replacement)
  • Nb-IoT Bee 95G, it uses Quectel BC95-G module. This module is a global regions module can work on different operators.
  • Nb-IoT Bee QG96, it uses Quectel BG96 module. This module supports mutli-bands. Except NB-IoT, It also support LTE Cat M1 & EGPRS.

 

Dragion LoRaST IoT module featuring LoRa® technology is a small wireless transceiver module offers a very compelling mix of long range, low power consumption and secure data transmission.It is designed to facilitate developers to quickly deploy industrial level LoRa and IoT solutions. It help users to turn the idea into a practical application and make the Internet of Things a reality. It is easy to program, create and connect your things everywhere. 

LoRaST's wireless part is based on SX1276/SX1278 which allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, and so on.

LoRaST's  mcu part use STM32l0x chip from ST, STML0x is the ultra-low-power STM32L072xx microcontrollers incorporate the connectivity power of the universal serial bus (USB 2.0 crystal-less) with the high-performance ARM® Cortex®-M0+ 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (192 Kbytes of Flash program memory, 6 Kbytes of data EEPa0 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals via industrial standard M.2 (NGFF) pin interface.

Dragion LoRaST featuring LoRa® technology is an open source product, it is based on the STM32Cube HAL drivers, with customer application examples, user can program the IoT module via USART1 , USART2 or STLINK. The factory firmware supports LoRaWAN 1.0.2 specification and user can use AT Command to set up it and use for their project directly. User can re-compile the firmware to support different LoRaWAN Frequency, includes: EU868, AS925, AU915, CN470, CN779, EU433, IN865, KR920, US915.
