SIM7020E NB-IoT Module For Pico

B1/B3/B5/B8/B20/B28 Frequency Band

The Pico-SIM7020E-NB-IoT is an NB-IoT (NarrowBand-Internet of Things) module designed for Raspberry Pi Pico. It supports multiple NB-IoT frequency band, can be controlled via serial AT commands, and supports communication protocols like HTTP/MQTT/LWM2M/COAP, etc. Due to the advantages of low delay, low power, low cost, and wide coverage, it is the ideal choice for IoT applications such as intelligent instruments, asset tracking, remote monitoring, and so on.

  • Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series boards
  • UART communication, serial AT commands control, multiple communication protocols support, multiple cloud platform support
  • Integrates 3.7V Li-po battery connector and recharge circuit, allows being powered from external rechargeable Li-po battery, or recharging it in turn
  • 2x LED indicators, for monitoring the module operating status
  • Onboard Nano SIM card slot for NB-IoT specific card
  • Comes with development resources and manual (MicroPython examples)
Raspberry Pi Pico Header Compatibility
  • The Pico Can Be SMD-Mounted (Left), Or Attached Via Female Header (Right)

  • Connecting With Other Expansion Module And Antenna



  1. Pico-SIM7020E-NB-IoT x1
  2. Antenna x1
  3. 20PIN female pin header x2
  4. 40PIN male pin header × 1
  5. 3.7V rechargeable Li-po battery x1

Cloud Communication

Supports Communication Protocols Including: TCP/UDP/HTTP/HTTPS/MQTT/LWM2M/COAP/TLS

Application Example

Via NB-IoT network, the Pico is able to fetch weather information by HTTP GET, and send its temperature to server via HTTP POST, then display it on webpage in real time.
