System LED

[stephen fleming]

Mhm ok, but where is the actual LED? Especially "purpose of the LED next to the charge LED on the board" . I can't see it - Please mark eg. in https://www.stdin.xyz/media/arm-board-party-1.jpg

The LED in question is located right next to the charge LED(marked Chgled) and is just called LED on the board and System LED on the expansion connector pin out sheet.
