1Product Overview
1.1 Product Background
RAK4200 Breakout Module is specifically designed to allow easy excess to the pins on
the module in order to simplify development and testing. The breakout board utilized is
of an Xbee form factor and its main purpose is to allow the RAK4200 stamp module form
factor pinout to be transferred to 2.54mm headers.
The module itself has the RAK4200 at its core, integrating an STM32L071 MCU and a
SX1276 LoRa® chip. It has Ultra-Low Power Consumption of 1.5uA in sleep mode, high
LoRa® max output power (19dBm) in work mode.
The module complies with LoRaWAN® 1.0.2 protocols. It also supports Lora® Point to
Point communication.
The RF communication capabilities of the module make it suitable for a variety of
applications in the IoT field such as home automation, sensor networks, building
automation, personal area networks applications (health/fitness sensors and monitors,
etc.).

3.1 Interfacing with the RAK4200 Evaluation Board
Warning
Before powering the RAK4200 Breakout Module, make sure you have installed the
included LoRa® Antenna. Not doing so might damage the board.
Connect your USB to UART converter to the pin header on the RAK4200 via a set of 4
dupont lines. Use Figure 2 for reference on wiring the device properly.
Figure 2 | Powering up and interfacing with the board
Go to your Device Manager by pressing: Windows + R and typing devmgmt.msc or
search in the Start Menu.
Look for Ports (COM & LPT) and Find the name USB-SERIAL CH340 and take note of
the COM Port Number as you will need it to connect with the board. You might have
another model number but the wording “USB-SERIAL” should be present in some form.
Note
Windows 10 should recognize the board and automatically install drivers, however if it is
missing in the COM & LP ports list you need to manually install the CH340 Drivers.

Open the RAK Serial Port Tool. Select the COM Port number (the one you noted in the
previous step) and set the Baud Rate to 115200. Click “OPEN” and you should be
connected to the board and be able to send commands.

3.2 Connecting to The Things Network (TTN)
The Things Network is about enabling low power Devices to use long range Gateways to
connect to an open-source, decentralized Network to exchange data with Applications.
Learn more about the Things Network here.
Log into your TTN account and go to the Console page:

3.2.1 Adding an Application
Once in the console you will notice that it is split in two large sections. We are
only going to be utilizing the "APPLICATIONS" section for the purpose of this
tutorial. Access it by clicking anywhere in rectangle.
Figure 6 | Adding an Application
Click the "add application" button and you will be greeted by the window in
Figure 7.

Figure 7 | Application parameters
Here are the things that you should take note in adding an application:
Application ID - this will be the unique id of your application in the Network. Please
note that characters should be in lower case, no spaces are allowed.
Description - this is a short and concise human readable description of your
application.
Application EUI - this will be generated automatically by The Things Network for
convenience and is a unique identifier of your application used for authentication of
devices
Handler Registration - handler you want to register this application to.
Fill in the Application ID and Description fields and leave the rest as is.
Click “Add application”
Upon successful application you should see the Application Overview page (Figure 8).

3.2.2 Registering a device
Now we need to add our actual device (RAK4200). Refer to Figure 8 again and
press the “register device” button that is marked with the red rectangle. Now
you need to set some device parameters (Figure 9)
