Raspberry Pi Pico SIM7020E NB-IoT Module HAT expansion board (19622)

The Raspberry Pi Pico SIM7020E NB-IoT Module HAT (19622 ) is a module for adding data transmission functions to the Raspberry Pi Pico microcontroller according to the NB-IoT standard (Narrow Band Internet of Things), a cellular communication standard for telemetry devices with low data rates. It supports operation in the bands: B1 / B3 / B5 / B8 / B20 / B28, can be controlled by serial AT commands, and supports communication protocols such as HTTP / MQTT / LWM2M / COAP, etc. With the advantages of low latency, low power consumption, low cost and wide coverage, it is an ideal choice for Internet of Things applications such as smart tools, tracking, remote monitoring, etc.

Key features:

• Standard Raspberry Pi Pico connector, supports Raspberry Pi Pico series expansion boards
• UART communication, serial AT command control, support multiple communication protocols, support multiple cloud platforms
• Integrates a 3.7V lithium-polymer battery connector and recharging circuit, allows you to receive power from an external rechargeable lithium-polymer battery or charge it alternately
• 2x LED indicators to monitor the operating status of the module
• Built-in Nano SIM card slot for a dedicated NB-IoT card
• Comes with development resources and manual (MicroPython examples)

The module supports communication via the cloud including the following protocols: TCP / UDP / HTTP / HTTPS / MQTT / LWM2M / COAP / TLS
