Overview
Specimen Track telecommunication HAT which supports global bands of NB-IoT, Cat-M, and GPRS, as well as GNSS positioning function. Due to its advantages like small size, low delay, and wide coverage, it is the ideal choice for IoT applications such as intelligent instruments, asset tracking, remote monitoring, e-health, and so on. Compared to SIM7080G, this module also supports GPRS (2G); compared to SIM7000C/E, it is more generic due to the global bands support.
Features
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
- Supports communication protocols such as TCP/UDP/HTTP/HTTPS/TLS/DTLS/PING/LWM2M/COAP/MQTT
- Supports GNSS positioning (GPS, BeiDou, GLONASS, Galileo)
- Onboard USB interface, to test AT Commands, get GPS positioning data, and so on
- Breakout UART control pins, to connect with host boards like Arduino/STM32
- SIM card slot, supports ONLY 1.8 V SIM card (3 V SIM card is not available)
- 2x LED indicators, easy to monitor the working status
- Baud-rate 300 bps to 3686400 bps
- Common baud-rate auto-negotiation 9600/19200/38400/57600/115200 bps
- Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
