Arduino NB-IoT 窄帶物聯網擴展板 中華電信專用 Dragino NB-IoT Shield B8 擴展通訊板

系統結構：

UART_TX和UART_RX連接到Arduino的D10 / D11。要使用其他引腳進行UART通信，用戶可以移除UART_TX和UART_RX跳線，並將這些接頭的右側連接到UNO的其他引腳。軟件串行引腳還需要在Sketch中進行相關更改。

SIM卡方向：

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.

Dragino NB-IoT Shield-B8

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 NB-IoT Shield 

Dragino NB-IoT Shield-B8 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.

Features：

• Support  900Mhz NB-IoT Bands
• Low power consumption
• Wide area coverage
• AT command to control
• Auto support 3.3v or 5v Arduino board
• Compatible with Arduino Leonardo, Uno, Mega2560, DUE… etc

Applications:

• Smart metering (electricity, gas and water)
• Facility management services
• Intruder and fire alarms for homes & commercial properties
• Connected personal appliances measuring health parameters
• Tracking of persons, animals or objects
• Smart city infrastructure such as street lamps or dustbins
• Connected industrial appliances such as welding machines or air compressors

System Structure:

UART_TX and UART_RX are connected to D10/D11 of Arduino. To use other pins for UART communication, user can remove the UART_TX and UART_RX jumper and wire the right side of these headers to other pins of UNO. The software serial pins also need to do related changes in Sketch.
