Overview
This is a telecommunication HAT for Raspberry Pi which supports global bands of NB-IoT, Cat-M, and GPRS, as well as GNSS positioning function. Due to its advantages like small size, low delay, and wide coverage, it is the ideal choice for IoT applications such as intelligent instruments, asset tracking, remote monitoring, e-health, and so on.
Compared to SIM7080G, this module also supports GPRS (2G); compared to SIM7000C/E, it is more generic due to the global bands support.

Features
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
Supports communication protocols such as TCP/UDP/HTTP/HTTPS/TLS/DTLS/PING/LWM2M/COAP/MQTT
Supports GNSS positioning (GPS, BeiDou, GLONASS, Galileo)
Onboard USB interface, to test AT Commands, get GPS positioning data, and so on
Breakout UART control pins, to connect with host boards like Arduino/STM32
SIM card slot, supports ONLY 1.8V SIM card (3V SIM card is not available)
2x LED indicators, easy to monitor the working status
Baudrate: 300~3686400 bps
Common baudrate auto-negotiation: 9600/19200/38400/57600/115200 bps
Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
