This means that the power-on procedure for the u-blox AWS IoT ExpressLink SARA-R5 module is 
NOT the AWS one, it is the original u-blox SARA-R5 one and there is no 

WAKE

 pin, see section 

8

. 

2.2

 

Standard kit contents 

This kit includes: 

 

the board with the SARA-R5 module, 

 

a cellular antenna, 

 

a Thingstream SIM card, which will have already been inserted into the board, 

 

an Asset Tracker Update Tool M.2 board. 

This  is  sufficient  to  allow  you  to  use  the  u-blox  AWS  IoT  ExpressLink  SARA-R5  module  from  an 
attached PC via the USB-C interface. 

 

The SIM card includes 250 Mbytes of data transfer with the cellular network and after that must 
be discarded. 

Not covered in this getting started guide, but also included in this kit, is an ESP32 MicroMod board 
that can be plugged into the M.2 socket on the board, allowing you to experiment with driving the 
module from a microcontroller; please refer to the 

ESP32 documentation

 for how to develop software 

using the ESP32 chip. 

2.3

 

User provided items 

To use the board via an attached PC, and to power it from USB, a USB-C cable is required. 

2.4

 

Third party purchasable items 

A variety  of  other 

SparkFun  MicroMod processor boards

each carrying  a different microcontroller 

(e.g. nRF5, STM32F4, Raspberry Pi Pico, etc.) are available to plug into the M.2 socket on the carrier 
board to use the module directly.

Set up your hardware 

Set up your hardware following the 

hook-up guide for the standard SparkFun MicroMod Asset Tracker 

Carrier Board

, noting the differences described at the start of section 

2

. 

3.1

 

Set up host machine 

To drive the u-blox AWS IoT ExpressLink SARA-R5 Starter Kit from an attached host machine, which 
is  ESSENTIAL  during  setup,  you  must  plug  the  provided  Asset  Tracker  Update  Tool  into  the  M.2 
socket on the carrier board. 

 

On the host machine you must install the drivers for the 

CH340 USB to UART bridge

.
