 ### Assembly Overview
 ![Example of a typical solution for remote environmental sensing including an Arduino® Nicla Sense ME, Portenta H7 and battery. Notice the orientation of the battery's cable in the board's connector. ](assets/niclaSenseMEBattery.png)
 
+**Note** : The NTC pin on the battery connector is optional. This is a feature allowing safer use and thermal shutoff of the PMIC.
