5.2.2.1

 

Power supply

 

The kit can be powered from a 3.7 V LiPo battery or via a USB cable from an external 5 V power supply. The 
battery is automatically charged when the system is connected to an external power supply. Both the IoT 
baseboard and the the PAS CO

2

 wing board switch automatically to the provided power supply, so no manual 

adaption is needed by the user.     

Note: The radar wing board must be manually switched to either battery or external 5 V supply 

–

 refer to the 

radar wing board user guide for more details.
