## Description

The SIM7028 NB-IoT HAT is a compact, low-power Raspberry Pi expansion board with NB-IoT (Narrow-Band Internet of Things) connectivity. It supports global NB-IoT bands and a wide range of communication protocols including TCP, UDP, MQTT(S), HTTP(S), CoAP, and TLS/SSL. Designed for applications requiring low latency, low power, and low throughput, this HAT is ideal for IoT projects such as remote monitoring, asset tracking, smart metering, and environmental sensing. It connects via the standard 40-pin GPIO header and is compatible with Raspberry Pi, Jetson Nano, Arduino, and ESP32 boards. Key Features Global NB-IoT Support – Works with NB-IoT bands worldwide via the onboard SIM7028 module Multiple Protocols – TCP, UDP, LWM2M, CoAP, DTLS, DNS, NTP, PING, HTTP(S), MQTT(S), TLS/SSL 40-Pin GPIO Header – Compatible with Raspberry Pi series boards, Jetson Nano, and more UART Control Pins – Connect to Arduino, STM32, or ESP32 via UART with configurable jumper USB-C Debug Interface – Onboard USB-to-UART converter for direct serial communication Nano SIM Slot – Compatible with NB-IoT SIM cards AT Command Control – 3GPP TS 27.007, 27.005, and SIMCOM enhanced AT commands Configurable Baud Rate – 2,400 to 460,800 bps (115,200 bps default) SIM Application Toolkit – SAT Class 3, GSM 11.11, USAT LED Indicator – Monitors working status at a glance Ideal For Remote environmental monitoring and smart metering Asset tracking and fleet management IoT sensor networks with low data throughput Smart agriculture and remote healthcare Package Contents 1× SIM7028 NB-IoT HAT 1× GSM Antenna 1× USB Type-A to Type-C Cable 1× 2×20-Pin Female Header 1× Standoffs Pack Warning: Per SIMCOM manufacturer restrictions, this product cannot be shipped to or supported in Iran, North Korea, Cuba, Sudan, or Syria.
