Supports Global Band NB-IoT Communication, Small In Size, Low Power Consumption
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)
