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
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**.

31 = Data Converters =
32
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.

309 You should see that the newly added integration is listed on the **Integrations** page.
310
311 Since we haven't received data from a device yet, the integration **Status** is shown as **Pending.**

316 = Verifying the receipt of data from the device =
317
318 Connect **S31B-NB** to transfer information. If the integration was performed without errors, after the transmission of the first telemetry, a new device with the name “xxxxx” will appear in the Devices → All. Also, you can verify the input and output data, respectively, before and after conversion in Data converters → UDP Uplink Converter NB/CB → Events.
