Dragino NBSN95A NB-IoT Sensor Nodes base on the Quectel BC35-G

The NBSN95A is a substitude version of Dragino NBSN95 due to IC shortage version. NBSN95A and NBSN95 has the same hardware performance and use the same image.

NBSN95A is a Long Range NB-IoT Sensor Node. It is designed for outdoor data logging and powered by 8500mAh Li/SOCl2 battery for long term use and secure data transmission. System Integrator can use NBSN95A to rapidly deploy NB-IoT sensor node for their IoT solution.NBSN95A is easy to program, create and connect things everywhere.

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.

To use NBSN95A, user needs to check if there is NB-IoT coverage in local area and with the bands NBSN95A supports. If the local operate support it, user needs to get a NB-IoT SIM card from local operator and install NBSN95 to get NB-IoT network connection.

NBSN95A is an open source project. It is based on the STM32L072CZT6 ultra-low-power ARM® Cortex®-M0+ micro controller. Developers can get completely software and hardware design files and adapter for their projects.
