Hi Heltec (and others),
I’m using a number of the AB02S boards and working through trying to find the ideal antenna. I’m trying to assess whether active gps antennas will actually work.
From what I have seen of the v1.1 schematic, it appears that there is either an error in the way bias t power is wired, or it was never intended to provide power for an active antenna. Either that or the schematic has the internal antenna and the U.FL connector back to front.
Either way can some one from heltec comment on the state of bias -t power on the AB02S?
