General Description
2.1
Overview
The NB-IoT & GNSS USB dongle is a cellular and GPS USB stick based on Quectel BG77. It has on-board LTE
& GNSS antennas.
The USB dongle features a microcontroller and wireless modem. The microcontroller
is an Atmel’s SAMD21G18A MCU which features a 32-bit ARM Cortex® M0+ core. The wireless modem is
BG77 which is an embedded IoT (LTE Cat-M1, LTE Cat-NB2 and EGPRS) wireless communication module.
BG77 wireless modem provides a maximum data rate of 589Kbps downlink and 1.12Mbps uplink. It
features ultra-low power consumption, provides data connectivity on LTE-TDD/LTE-FDD/GPRS/EDGE
networks, and supports half-duplex operation in LTE networks. It also provides GNSS to meet customers’
specific application demands
The USB dongle provides rich sets of Internet protocols, industry-standard interfaces
(USB/UART/I

C/Status Indicator) and abundant functionalities. The board offer a high integration level
and enables integrators and developers to easily design their applications and take advantage of the board
low power consumption, many functionalities, and USB drivers for Windows 7/8/8.1/10, Linux and
Android.
The kit is a rich hardware board that can be used for the latest 5G wireless technology and enables a
variety of smart and 5G applications for devices, and acts as a great educational tool for learning about
5G and 32-bit application development. It enables large number of applications such as wireless POS,
smart metering, tracking, smart transportation, smart buildings, smart city, and smart homes.
The board is also compatible with Arduino and Arduino software (IDE). Arduino sketches and examples
are provided with the kit and additional sketches can be developed and uploaded to the board.
