15 15  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.
16 16  
17 17  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**.
