Please describe your issue below:

Does the Edge2 need a regulated input voltage? On the documentation I received with my Edge2 board, it shows an input voltage range of 9-20V. If I have a battery with a nominal voltage of 14.4V and a range of 16.8V-12V (fully charged to cutoff), can I just connect the battery to the Edge2 board through the USB-C PD port? The alternative would be to use a regulator to supply the Edge2 board with a fixed 12V. I want to avoid issues, so please let me know what the best practice would be.

Hello
Sorry for the late reply!
For the USBC power supply of Edge2, as long as the voltage is within 9-20V and the power can be satisfied;
If there is no other external device related to the FPC, it is not necessary to switch to a stable 12V level.
If there is a connection, such as FPC LCD screen, it should be evaluated according to the LCD backlight input parameters;
Hope this can help you !
Thanks!
