Waveshare SIM7028 NB-IoT HAT for Raspberry Pi with Global Band NB-IoT Communication Support
Couldn't load pickup availability
The SIM7028 NB-IoT HAT supports global bands and a variety of communication protocols, including MQTT(S), HTTP(S), TCP, UDP, and others. It is made for low-power, low-latency Internet of Things applications. Jetson Nano, Raspberry Pi series boards, and other microcontrollers may all use it because it has a standard 40PIN GPIO header. With a USB-to-UART chip for flexible communication, a nano SIM card slot, UART control pins for external connections, an onboard Type-C interface for software debugging, and a range of IoT applications, including asset tracking, smart meters, remote healthcare, and smart city solutions, this module is incredibly versatile. It ensures simple development and integration by providing documentation and online resources with sample codes for the Raspberry Pi, Jetson Nano, Arduino, and ESP32.
