1 Introduction

The Global LTE IoT Starter Kit is a next-generation System-on-Module IoT solution, enabling the design of cellular connected edge devices, for operation in Europe.

Powered by AT&T IoT services available through Avnet, this kit provides a complete development environment for sensor-to-cloud applications and services.

Designed to be used for both prototyping and production, the slim form-factor LTE System Board with it’s regional certifications and pre-registered Micro-SIM card for AT&T M2X service (included in the kit), as well as versatile expansion options, together provide a high level of enablement that facilitates easy IoT deployment and reduction in overall risk.

The Starter Kit features a small (79.5 mm x 30 mm) LTE System Board built around a Wistron NeWeb (WNC) M18QWG global LTE Cat-4 modem module. The M18QWG module provides cellular modem functionality plus an applications processor core dedicated for user applications, eliminating the need for an external host processor. A rich set of embedded system peripherals, controllable through the user’s application code, are easily accessible via a 60-pin expansion connector and 2x6 peripheral module header. This enables easy system customization with application specific sensors and I/O interfaces through the addition of user-created or off-the-shelf plug-in boards. The LTE System Board includes ambient light, temperature and accelerometer sensors onboard, for out-of-box demonstration examples.

User application code runs directly on the M18QWG module, leveraging the OpenEmbedded software framework for Linux application development. A Software Development Kit (SDK) specific to the M18QWG module provides the necessary API calls to access hardware peripherals and system resources. Application code built with the SDK is loaded into the M18QWG module through a USB interface on the development board eliminating the need for external proprietary JTAG cables.

Cloud application development is supported by AT&T’s M2X Data Services and Flow Designer.

- M2X is a cloud-based, fully managed data storage service for connected machine-to-machine (M2M) devices

- Flow Designer provides a visual editing environment for the design of connected applications, enabling IoT developers to rapidly create and deploy innovative new applications.

Design goals of this LTE IoT Starter Kit included the following:

- Provide a versatile prototyping- and production-ready (cost-optimized) platform for development and productized custom applications using WNC M18QWG Cat.4 cellular modem and GPS, for deployment Globally via AT&T’s partner LTE networks

- Provide hardware expansion examples using:

- PmodTM-compatible peripheral boards,

- Custom breakout board

- Provide reference designs that accelerate development of applications for popular use cases

- With the provided AT&T SIM starter pack, demonstrate the use of:

2.1.4 Expansion Interfaces for System-Level Prototyping

Two interfaces facilitate the adding of custom hardware to the LTE System board: System expansion interface (1.8V I/O) is a 60 pin expansion connector (Samtec ERF8 /

ERM8 series) on the underside of the system board. WNC module peripherals are accessible via this interface at 1.8V signalling levels, if 3.3V (or 2.5V) levels are required by the user’s custom circuitry, then voltage translator devices must be added to the user’s board.

Pmod™-compatible interface (3.3V I/O) is 6x2 pin connector facilitates an easy to use interface via I2C or SPI peripherals, for access to a wide range of Pmod™ peripheral boards. The relaxed pitch of this connector and low pin count of these interfaces also permits wiring-in other 3.3V expansion boards (eg. MikroElektronika Click modules or Grove sensor boards) for prototyping system-level solutions

3 LTE System Board Functional Description

The following sections describe the key functional blocks on the AT&T LTE IoT System Board

3.1 LTE Modem Module (WNC M18QWG)

The M18QWG is a SoC modem module from Wistron NeWeb Corporation (WNC) that provides Cat.4 LTE cellular wireless connectivity plus GNSS location tracking, as well as a full-featured application processor subsystem with peripheral interfaces and functions uniquely designed to address the power/performance/cost constraints of IoT and M2M applications.

The quad-core ARM Cortex A7 applications processor on this module is based on Qualcomm’s MDM9207 architecture and offers (OFDMA-related) software based signal processing capabilities that significantly exceeds the efficiency of traditional ARM based communications processors.

Host mode: The WNC module will normally operate in “host mode”, where one of the ARM Cortex A7 cores in the on-module Qualcomm MDM device is reserved for use as the system processor for user applications. (The other three A7 cores are dedicated to the modem functions).

Modem mode: WNC module operation in “slave mode” (as a peripheral to an external processor interfaced to the WNC module via USB interface) is not currently supported

The M18QWG also provides system peripheral interfaces and library support for these, (eg. USB 2.0, I2C, SPI, SGMII, PCM, HSIC, UIM, UART*, SDIO*)

Refer to the next section pinout listing of the 60 pin Expansion Connector (Samtec ERF8) for detail regarding the M18QWG module I/O that is accessible to the User

Documentation for the M18Q2 series WNC North America module that shares similar functionality is available at the FCC certification website https://fccid.io/NKRM18Q2

3.2 Expansion Connector

The peripheral interfaces of the WNC M18QWG module are made available to the developer for custom system design via the board’s 60 pin Expansion Connector.

This is interface is implemented using a 2x30 pin, 0.8mm pitch, Samtec ERF8 series connector, providing a robust, space-efficient and economical stacking solution that is especially attractive for cases where small overall physical size of the final product is vital.

3.3 2x6 Pin Peripheral Connector

The 2x6 Pin Peripheral Connector is compatible with a subset of Pmod™ peripheral boards from Digilent, Maxim, Measurement Specialties (TE Connectivity) and others.

The pinout of this 2x6 pin right-angle socket connector is derived from the I/O signal assignments defined in the Digilent Pmod™ Interface Specification for SPI and I2C serial interfaces.

Note however, that dual-row I2C Pmod peripheral boards in many cases may not be fitted to this board, as their duplicate SCL and SDA pins are not accommodated by the combo SPI plus I2C interface pinout assignments implemented on the LTE System board.

3.4.1 SIM Interface (3FF Micro-SIM Connector)

The UIM (User Identity Module) interface is implemented with a Micro-SIM connector that interfaces a removable 3FF sized AT&T SIM card to the WNC module.

- This SIM interface includes the necessary ESD protection devices

- It is powered from the WNC module and will auto set to 1.8V or 3.0V upon SIM negotiation. The UIM_DETECT input pin of the M18QWG module is driven from the UIM connector

circuit:

- If SIM card is present, UIM_DETECT = High (1.8V / 3.0V)

- If SIM card is absent , UIM_DETECT = Low (GND)

Table 5 – SIM Card Interface Connections

Notes:

- Power to the System board must be turned-off when removing or inserting the SIM card!

- The SIM card connector is not spring-loaded. To remove the SIM: Turn the board upside-down. Eject the SIM by pushing from inside, outward to board-edge

The WNC module firmware limits UART1 to a predefined system function specifically for:

“High Speed Data Transfer”

WNC UART1 modem interface as implemented via the USB Compound Device, is available through either:

 the MicroUSB connector, or  the 60-pin Expansion connector

As tabled on the previous page, additional UARTs (in service of the other processor cores) also communicate over the same USB interface

3.4.4 UART2 – Software Debug UART Interface (3-pin header)

WNC UART2 is limited by the module firmware to performing the predefined system function of: “Software Debug UART”

The I/O levels of this UART are level-shifted, with it’s TX, RX and GND signals made available on a 3-pin header (J9) to facilitate external connection to a 3rd-party USB-to-Serial debug cable

Table 8 – Software Debug UART Header (J9)

Page 26

3.4.5 Voltage Level Translation (1.8V / 3.3V)

SPI1 and UART2 interfaces plus two GPIOs (GPIO93 and GPIO95) from the WNC module are level-shifted to 3.3V levels by Fairchild FXLA108BQX octal bi-directional level-translator device

In addition, the I2C peripheral interface bus from the WNC module is also level-shifted, using an FXMA2102L8X 2-bit level-translator that is compatible for use with open-collector outputs

The level-shifted 3.3V signals are routed to the following connectors:

 the Pmod-compatible 2x6 peripheral connector (J8) and  the Software Debug UART 3-pin header connector (J9)

A single ADC input is provided on the WNC module.

 This inputs to a 16 bit convertor, sampled at 2.4MHz for an ENOB of 15 bits  Analog Input Bandwidth is 100 kHz (typical)  The ADC’s input range is 0.1V to 1.7V

A shorting link across jumper JP2 connects one of the following sources to this ADC input:

Table 9 – ADC Input Source Selector (JP2)

Note! Two issues should be noted that limit the utility of the ADC input on the initial production boards:

a) ADC input source selection via JP2 is not possible unless the R50 “default” resistor is removed b) The ADC’s input voltage limit could be exceeded if the Ambient Light Sensor is exposed to an

excessively bright light source, resulting in potential damage to the module. To prevent this, it is recommended that light-levels must be restricted using some form of optical filter placed over the U3 light sensor (see U3 location below)

The LIS2DW12 is a 2017-released, ultra low-power, MEMS 3-axis smart accelerometer from ST Micro. It has 16-bit output and can be configured (with 5 settings in either mode) to prioritize:

 ultra-low power consumption (< 1 µA @ ODR = 12.5 Hz), or  very low-noise performance (down to 90 µg/√Hz)

Other features include:

 Selectable acceleration full-scale range of ±2/±4/±8/±16 g  32-level embedded FIFO (for measurement buffering)  Thermal stability over the full -40 to +85 °C industrial temperature range  Embedded temperature sensor  1.8V operation and I/O levels  50 nA power-down mode  Dedicated internal engine for motion

and acceleration processing:

o Free-fall wakeup o 6D/4D orientation o Tap and double-tap recognition o Activity/inactivity recognition o Portrait/landscape detection

The LIS2DW12 is used as a slave device (address=0011001 b7) on the WNC module’s I2C peripheral bus. The SA0 input of the LIS2DW12 device is tied high, but this signal is pinnedout to test-point SA0 to facilitate potential modification of (LSB) of the device I2C address

Table 10 – LIS2DW12 Interrupt Outputs

Both interrupt outputs are by default connected to the WNC module (GPIO06 and GPIO07) If one or both of these WNC GPIOs are required for a different purpose, they may be disconnected from the LIS2DW12 device by removing resistors R48 and R49

Table 16 – Summary of LTE System Board Voltages

3.5.1 VIN

Unregulated DC input power (in range of 4.5V to 16V) can be supplied to the LTE System board via one of three different input interfaces:

 the “PWR IN” MicroUSB connector (J6)  the 60-pin Expansion Connector (J1)  the 2-pin VIN and GND aux connector (J10, unpopulated)

In the IoT Starter Kit, the provided 5V 2.5A AC/DC power adaptor applies power to the LTE System board via the “PWR IN” MicroUSB (J6) connector

The input supply voltage can be measured by placing voltmeter test leads across the unpopulated DC aux input connector pads (J10)

3.5.2 3V8 (VCC)

3.8V @ 3 A max, An onboard ON Semi NCP3170 buck switching regulator supplies the WNC module’s VCC input requirement. Regulators on the WNC module then convert this voltage down to the lower core voltages required

The REG_EN regulator enable input:

 is pulled high following power-up via an RC delay circuit (enables the 3V8 output)  can be pulled low from the 60-pin Expansion Connector (to disable the 3V8 output)

Power Good status of the 3V8 output supply rail can be verified in two places

 LED1 - illuminates green when the circuit is correctly powered and REG_EN is high  PG test point - this should be high (when circuit is powered and REG_EN = high)

An unpopulated 2-pin header site (JP1) is provided for 3V8 current measurement. To use this feature, the following board modification is required:

 Zero-ohm resistor R47 must be removed  A 2-pin header connector JP1 must be added  The meter test leads must be placed across the pins of JP1  After completion of current measurements, a shorting link (JPR1) must be fitted

across these JP1 header pins

Page 35

Page 36

The 3V8 module supply is filtered per WNC recommendations using the following circuit

3.5.3 1V8_VREF (VREF)

1.8V @ 100 mA max. Supplied by the VREF pin of the WNC module. This provides 1.8V power to the following circuits:

 The VREFA input of the 1.8V/3.3V level-shifter devices (U9 and U10)  The LIS2DW12 accelerometer  The LNA in the GNSS/GPS antenna circuit  Some discrete pull-up resistors

3.5.4 VCC_UIM_SIM (UIM_VCC)

1.8V or 3.0V @ 150mA max. Supplied by the UIM_VCC output pin of the WNC module This voltage is auto set on SIM negotiation and provides 1.8V or 3.3V power to:

 The “User Identity Module”, ie. the removable SIM Card.

3.5.5 3V3

3.3V @ 150 mA max. Supplied by the onboard On Semi NCP114 LDO regulator. This supplies 3.3V power to the following circuits:

 The VREFB input of the 1.8V/3.3V level-shifter devices (U9 and U10)  The Pmod Interface (J8)

3.7 WNC Module Power Control and State Interfaces

The following 6 signals fall in this category:

Table 17 – Control and State Signals

RESET

The RESET signal on the 60-pin Expansion Connector may be used as an input or output. This functions in parallel with the onboard SW1 pushbutton switch. The WNC module is reset by a logic low on this signal for 3 seconds or longer

WAKEUP_IN and WAKEUP_OUT

For power-sensitive applications, this mechanism allows the modem and an external host to enter low power states whenever possible, with the other side then waking it when required.

If the modem receives data while the host is in low power state, then it must wake-up the host. If the host needs to transmit data while the modem is in low power state, then the host must be

able to wake-up the modem. The interface consists of two signals:

WAKEUP_IN is driven by an external host and received by the modem WAKEUP_OUT is driven by the modem and received by the host.

Each side can wake the other side by toggling it’s wakeup signal high, or allowing the other side to go to sleep when not needed by toggling wakeup low.

Table 18 – WAKEUP_IN and WAKEUP_OUT

Page 38

REG_EN and POWER_ON REG_EN controls the main 3V8 regulator and is pulled high (enabled) following power-up via an

onboard RC delay circuit. This signal is also available on the 60-pin Expansion Connector for external ON/OFF control of the onboard 3V8 and 3V3 regulators. This allows system power to be controlled by eg. a low-power MCU on the User’s custom hardware

Figure 15 – Sleep and Power Control of WNC Module

POWER_ON is the power control input to the WNC module. This is made available on a test-point

(“PWR”) but is otherwise unused in this design. (Not available on the 60-pin Expansion Connector) Note: In the event the User application also needs control of the POWER_ON input, this requires

rework of the LTE System board as R11 will need to be removed

WWAN_STATE This signal drives the WWAN LED (Amber color) and is normally used to indicate network status, but is control from the User application so can be repurposed if necessary
