Product descriptions
Supports Global Band NB-IoT Communication, Small In Size, Low Power Consumption
Features At A Glance
The SIM7028 NB-IoT HAT is a small size, low-power, and powerful Raspberry Pi HAT with NB-IoT (Narrow-Band Internet of Things) function, supports global band and supports TCP, UDP, LWM2M, COAP, DTLS, DNS, NTP, PING, HTTP(S), MQTT(S), TLS/SSL, etc. It is designed for applications that need low delay, low power, and low throughput, also suitable for IoT applications such as meters, remote control, asset tracking, remote monitoring, remote healthcare, bicycle-sharing, and so on.
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards and Jetson Nano, etc.
Supports TCP, UDP, LWM2M, COAP, DTLS, DNS, NTP, PING, HTTP(S), MQTT(S), TLS/SSL, etc.
Onboard Type-C interface for software debugging
Onboard UART control pins, for connecting with host boards like Arduino/STM32
1x LED indicators, easy to monitor the working status
Onboard USB to UART chip, the UART communication pin can be configured via jumper
Onboard nano SIM card slot, compatible with NB-IoT specific card
Baudrate: 2400bps ~ 460900bps (115200bps by default)
Control via AT commands (3GPP TS 27.007, 27.005, and SIMCOM enhanced AT Commands)
Supports 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)
