SCH for J45 information

Hi,

My JETSON Nano is not connected to internet thus the date & time settings are always incorrect after each restart.
Behind the board there is a J45 footprint but there is no information into the start guide.
I think is for a lithium battery.

Could you provide information about it?

Thanks

Yes, J45 is for backup battery/super cap of RTC. Coin cell CR1225 is recommended.

Thank you for your help

Can someone please guide on how to install the cell holder onto the board? Would really appreciate.

You can refer to schematic/assembly/pcb files of carrier board to install that. https://developer.nvidia.com/embedded/dlc/Jetson-Nano-Carrier-Board-Reference-Design-Files
