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

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

5.3 LED3: BG96 PWR Status
Note that the status indicated by this LED is inverted!
LED3 = ON when BG96 module is in Power Down mode
LED3 = OFF when BG96 module is active
The state of the BG96 module and this BG96 PWR status LED can be changed
by the host MCU, or by the User doing one of the following:
pressing PWRKEY button switch S1
entering an AT+QPOWD command

Page 12
6 PWRKEY Pushbutton Switch (S1)
The PWRKEY button switch provides two functions to the User. It can be used to:
Wake-Up or Power-Down the BG96 module
Manually exit the BG96 module’s Power Saving Mode (PSM)
7 SIM / eSIM Interface
The BG96 Shield is fitted with a preconfigured Infineon eSIM device. If you want to use a removable SIM
card, then SW4 must be set accordingly and the SIM should be activated on the carrier’s website
To insert a SIM card, slide the metal retaining clip in direction of the PWR KEY Push-button switch, then lift
this up and inserting the SIM with notched corner facing outwards as shown below. Lock the SIM into place
by pressing on the SIM holder and sliding the metal retaining clip back in the other direction.
