Sinovoip, well-known like single-board computer manufacturer of Banana Pi, released other pictures of IoT module which uses NB-IoT (NarrowBand Internet of Things). This IoT network uses Vodafone in trial version in Czech Republic (2017). NB-IoT is standard Low Power Wide Area Network (LPWAN) used for communication of IoT devices(Internet of Things).
BPI-BC95 NB-IOT contains STM8L152 - low power MCU. The upload of code is through SWD.
NB-IOT also contains temperature/humidity sensor (Si7021) and sensor of pressure (BMP085).
On the board are microUSB, RGB LED, connector for external antenna and connector for battery.
The dimension of board is (53 X 43 mm) and connectors can be fit to Arduino Uno Rev.3. connectors.
The power consumption is lower than 20uA.
The IoT module uses IoT chip by Quectel BC95-SL. Specifications Quectel BC95:
Power supply: 3 - 4.2V
Bitrate: up to 100kb/s
Band: 900MHz (B8)
Peripherals: SIM, 2x UART, ADC, antenna
