The Waveshare NB-IoT HAT is a compact expansion board for Raspberry Pi, designed for narrowband Internet of Things (NB-IoT) applications. It uses the SIM7020E module to enable wireless communication in regions like Europe and Asia, supporting specific LTE bands such as B1, B3, B5, B8, B20, and B28.
For IoT projects like remote monitoring or asset tracking, this HAT provides reliable, low-power connectivity. It allows developers to send and receive data efficiently, ideal for scenarios requiring long battery life and wide coverage, such as smart meters or environmental sensors.
- Compatible with all Raspberry Pi models via serial AT commands
- Supports protocols including LWM2M, COAP, MQTT, TCP, UDP, HTTP, and HTTPS
- Features a USB interface for power or debugging, and breakout UART pins for other host boards
- Includes a SIM card slot and LED indicators for status monitoring
- Adjustable baudrate from 300bps to 921600bps, with onboard voltage translator for 3.3V or 5V logic
- Compact size of 30.5mm x 65.0mm, consuming around 18mA in idle mode
This HAT fits well into DIY electronics projects for hobbyists and professionals needing efficient wireless solutions, ensuring compatibility with local NB-IoT networks.
