SIM7028 NB-IoT HAT with GSM Antenna Onboard 40PIN GPIO Header for Raspberry Pi 5/4B/3B+/3B/2B/Zero/Zero 2W/Jetson Nano,etc, Supports Global Band NB-IoT Communication, 2400bps ~ 460900bps Baudrate

Introduction
The SIM7028 NB-IoT HAT is designed for applications that need low delay, low power, and low throughput, also suitable for IoT applications such as meters, remote control, asset tracking, remote monitoring, remote healthcare, bicycle-sharing, and so on.

Features
Compatible with Raspberry Pi Zero/Zero 2/2B/3B/3B+/4B, and Jetson Nano, etc.
Global band Support: supports communication protocols including TCP, UDP, LWM2M, COAP, DTLS, DNS, NTP, PING, HTTP (S), MQTT (S), TLS/SSL, etc.
Onboard Type-C interface for software debugging
Onboard UART control pins, for connecting with host boards like Arduino/STM32
1x LED indicators, easy to monitor the working status
Onboard USB to UART chip, the UART communication pin can be configured via jumper
Onboard nano SIM card slot, compatible with NB-IoT specific card
