2. General Description

Overview

The NB-IoT & GNSS IoT phone is like a real phone. It is a cellular NB-IoT and GPS device that can be used for the 5G wireless technology. The phone has a keypad and full-color TFT LCD display with LTE & GNSS antenna connectors (or on-board antennas). The phone is a powerful board that features a microcontroller, wireless modem, keypad, a full-color TFT LCD, re-chargeable battery, and SD card. The microcontroller is an Atmel’s SAMD21G18A MCU which features a 32-bit ARM Cortex® M0+ core. The wireless modem is BG96 which is an embedded IoT (LTE Cat-M1, LTE Cat-NB1 and EGPRS) wireless communication module. BG96 wireless modem provides a maximum data rate of 375Kbps downlink and 375Kbps 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 LCD is a full-color, 2.4 inch with 240×320 pixel resolution. The Keypad consist of 25 keys covering numbers, alphabets, characters, Up/Down/Right/Left buttons, and functions buttons. The IoT phone can be powered from either a UCB power source or a re-chargeable battery.

The IoT phone provides rich sets of Internet protocols, industry-standard interfaces (USB/UART/I2C/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 NB-IoT phone mimics real cellular phone and 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 NB-IoT phone 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.

  • SPI can be programmed through any of general-purpose pins.

PIN Description

PrecautionThe NB-IoT phone runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board

 

BG96 chipset

All functionality of the BG96 shipset shall be implemented excluding the following features. That is, the following features are not supported [1][2].

  • Audio, Earphone, and Codes are not supported.
  • PCM and I2C are not supported
  • PSM_IND and AP_READY are not supported

 

Interface between SAM21D and BG96
