SIM7028 NB-IoT HAT expansion card (EN)

TheSIM7028 NB-IoT HAT (EN) expansion card is an energy-efficient module that extends the capabilities of the Raspberry Pi single board computer, enabling it to operate on a NB-IoT (Narrowband Internet of Things) network and interact with Internet things in different countries and regions. The module has a compact size and low power consumption, making it ideal for IoT applications where reliability and low power consumption are important.

The module supports TCP, UDP, LWM2M, COAP, DTLS, DNS, NTP, PING, HTTP(S), MQTT(S), TLS/SSL, etc. It is designed for applications that require low latency, low power, and low bandwidth.

With this module, the Raspberry Pi can easily connect to an NB-IoT network to collect and transmit data from various sensors and devices in real time, opening up a wide range of possibilities for creating IoT projects such as remote monitoring, control, measurement, counters, remote control, asset tracking, remote healthcare, bike sharing, and more.

Key features:

• Has a standard Raspberry Pi 40PIN GPIO expansion connector and supports Raspberry Pi and Jetson Nano series boards, etc.
• Supports TCP, UDP, LWM2M, COAP, DTLS, DNS, NTP, PING, HTTP(S), MQTT(S), TLS/SSL, etc.
• Has a built-in Type-C interface for software debugging
• Has built-in UART control pins for connecting to host boards such as Arduino/STM32
• Equipped with LED indicator to monitor the working status
• USB - UART can be switched with a jumper
• Has a built-in nano-SIM card slot, compatible with a dedicated NB-IoT card
• Provides transmission speed: 2400 bps 460900 bps (115200 bps by default)
• Controlled by AT commands (3GPP TS 27.007, 27.005 and SIMCOM, enhanced AT commands)
• Supports the SIM application toolkit: SAT Class 3, GSM 11.11, USAT
• Comes with online development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/ESP32)
