NB-IoT / Cat-M(eMTC) / GNSS HAT for Raspberry Pi, Globally Applicable

Description of product

Description

This is a telecommunication HAT which features multi communication functionalities: NB-IoT (NarrowBand-Internet of Things), Cat-M (aka eMTC, enhanced Machine Type Communication), and GNSS (Global Navigation Satellite System).

With the developing of telecommunication technology LTE, 2G/3G networks are fading away, the future world would be dominated by IoT technologies consisting of low bandwidth NB-IoT/Cat-M and high bandwidth 4G/5G standards.

This HAT supports global bands of NB-IoT and Cat-M, as well as 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.

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
