1 Introduction
The Telus LTE-M IoT Starter Kit integrates three boards (stacked via their Arduino connectors):
Avnet Quectel BG96 Shield (LTE Cat-M1 and NB-IoT cellular modem and GPS board)
STMicro NUCLEO-L496ZG MCU Board
STMicro X-NUCLEO-IKS01A2 Sensor Board
Enabled with the new Telus LTE-M IoT service plus free online development tools, product developers are
equipped with a versatile, rapid prototyping platform, for defining innovative new custom IoT products
The low-power Quectel BG96 IoT wireless module on this board is configured and operated via an
extensive set of AT commands. Mbed OS5 software examples are provided, enabling rapid application
development, using Mbed online IDE, libraries and software stacks (SSL, MQTT, COAP etc.)
The 2nd use-case of the BG96 Shield is a Pmod-connected modem peripheral, for host boards that support
a Pmod-compatible interface.
The 3rd use-case of the BG96 Shield is a USB-connected modem, supporting three serial ports (via USB):
UART1 - data transmission and AT command communication
UART2 - module debugging and log output
UART3 - output of GPS data / NMEA sentences
The power supplied to this board may be:
5V DC sourced from USB connector or Arduino shield connector, or
3.3V DC sourced from Pmod connector
VBAT from the battery connector
The provided wide-band LTE flex antenna, delivers good signal strength across multiple LTE frequency
bands. A passive GPS flex antenna is also provided
1.1 BG96 Module Features
Based on Quectel BG96 LPWA module
Multiple operating modes: Cat-M1, Cat-NB1, EGPRS
Global LTE bands support
oCat-M1/NB1: B1 B2 B3 B4 B5 B8 B12 B13 B18 B19 B20 B26 B28 B39 (B39 for M1 only)
oEGPRS: 850/900/1800/1900 MHz
Low Power Consumption
oApproximately 10 uA in PSM mode
GNSS (GPS, GLONASS, BeiDou/Compass, Galileo, QZSS)
VoLTE Voice over LTE support (M1 only. Not pinned-out on the BG96 Shield!)
PCM digital audio interface (Not pinned-out on the BG96 Shield!)
Connectors
oSIM Card holder
oArduino Shield interface
oPmod interface
Software
oModem and GPS support via AT Commands
oBuilt in support for PPP/TCP/UDP/SSL/TLS/FTP(S)/HTTP(S)
oSupport for major operating systems (Android, Linux, Windows)
oSupport for Mbed OS5 for integrated embedded development

Figure 2 –Location of Key Components on the BG96 Shield
Notes:
The provided USB cable should be connected to the ST-Link/UART interface of the MCU board.
The only time this USB cable can be connected to the BG96 board (as shown in above photo) is
when the BG96 board is used standalone for eg. the following use cases:
a) Standalone BG96 modem or GPS testing (as detailed in Appendix A and B)
b) In the event of needing to upgrade the Quectel firmware on the modem module

4 Configuration Switches
The slide switches (Wurth WS-SLTV series) on the BG96 board have "opposite-side connection"!
ie. When red slider is positioned across pins 1-2, the circuit of pins 2-3 is bridged !!!
The highlighted switch settings in the table below, match the red slider positions

4.1 SW1: Selection of Input Voltage Source
Slider switch SW1 determines if the supply voltage to the BG96 module is from:
a) the onboard 3.8V voltage regulator (which is supplied from 5V pin on Arduino connector), or
b) the Pmod 3.3V pins or external battery connector
For use in this Starter Kit, the output of the onboard regulator should be used
4.2 SW2, SW3: Selection of UART0 Connection to Arduino Pins
Note that for use with a NUCLEO-L496ZG microcontroller board, UART0 of the BG96 must be routed
to the pins that match the D2 and D8 pins of the Arduino Shield interface standard
