11 11  This document guides you on integrating Dragino **-NB** and **-CB** series devices data with ThingsBoard. For this guide, we use ThingsBoard Cloud, which is one of the ThingsBoard versions that allows you to try it for free.
12 12  
13 13  The **NB series** devices end with the suffix **-NB**, and the **CB series** devices end with the suffix **-CB**. For example, **S31B-NB** is an **NB device**, and **S31-CB** is a **CB device**.

23 +First, we will add a device to simulate data using MQTT. This device does not represent a real physical device but serves as a common virtual device for all Dragino NB/CB devices.

53 +Then, select the operating system you are going to use with the **Mosquitto MQTT Broker**. This example shows sending a command from a computer running **MacOS**. First, install the necessary client tools on your computer.

63 +[[image:new-device-check-connectivity.png||height="522" width="500"]]
64 +
65 +
66 +On the terminal, enter the command you copied. This command sends the MQTT payload **{temperature:25}** as telemetry data from a virtual device named **'me'**. Of course, you can replace **'me'** with a device name or use the wildcard character **'+'** to match any device name.

33 33  In **ThingsBoard**, **Data Converters** are components used to transform incoming or outgoing data between different formats, typically to convert raw telemetry data from devices into a structured format that ThingsBoard can understand, or vice versa.
