Applicable Region

SIM7020E is mainly applicable in Europe, Asia, Africa, Australia.
Please check the supported bands according to your local service provider when placing order.

Overview

This is an NB-IoT (NarrowBand-Internet of Things) HAT for Raspberry Pi, controlled via serial AT commands, supports communication protocols like LWM2M/COAP/MQTT, 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.

Features

• Raspberry Pi connectivity, compatible with any revision
• Supports communication protocols such as LWM2M/COAP/MQTT/TCP/UDP/HTTP/HTTPS, etc.
• Onboard USB interface, for power supply OR debugging
• Breakout UART control pins, to connect with host boards like Arduino/STM32
• Onboard voltage translator, 3.3V by default, allows to be switched to 5V via onboard jumper
• SIM card slot, supports NB-IoT specific card
• 2x LED indicators, easy to monitor the working status
• Baudrate: 300bps~921600bps (115200bps by default)
• Control via AT commands (V.25TER, 3GPP TS 27.007, and SIMCOM AT Commands)
• Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32/Python)
