Nova LTE direct UART connection

This post would have been in reply to this closed thread:

Minding the level shifters to 1.8V logic, you only need to “scrape-off” one via to gain direct uart communication to the Nova LTE board. Removing top layer of the via just left to the RESET solder pad will disable USB communication. With basic magnification an a sharp x-acto blade, this is a relatively quick and easy job.

Also, the module will work with direct Li-Ion voltage power on USB VCC pin. (Be sure to have low-ESR cap at the mating USB connector.) No need to remove regulator.
