Raspberry Pi SIMCOM SIM7070G module NB-IoT/Cat-M/GPRS GNSS positioning expansion board

Origin:Mainland China

Model Number:SIM7070G Cat-M/NB-IoT/GPRS HAT

Product Description

SIM7070G Cat-M/NB-IoT/GPRS HAT supports NB-IoT, Cat-M and GPRS in the global frequency band, with GNSS positioning function, compact size, low communication delay, and wide coverage. It is very suitable for smart meters, asset tracking, Internet of Things applications such as remote monitoring and electronic medical care. Compared to SIM7080G, I support GPRS (2G), and compared to SIM7000C/E, I support global network frequency bands, which are universal.

Based on Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboards

Support TCP/UDP/HTTP/HTTPS/TLS/DTLS/PING/LWM2M/COAP/MQTT and other protocols

Support GNSS positioning (GPS, Beidou, GLONASS, Galileo)

Onboard USB interface, which can be used to test AT commands, obtain GPS positioning information, etc.

Lead out UART control pins, which can be connected to main control boards such as Arduino/STM32

Onboard SIM card slot, only supports 1.8V SIM card (3V SIM card is not supported)

Onboard 2 LED indicators for easy viewing of the module's operating status

Support serial port baud rate range: 300 ~ 3686400 bps

Support self-adapting several common baud rates: 9600/19200/38400/57600/115200 bps

Provide complete supporting information manuals (Sample programs such as Raspberry/Arduino/STM32)
