![]() Connect it to a 50 ohm antenna and who knows what range you'll get, its all very haphazard. But this not only detunes the antenna, it also provides an unknown impedance out. ![]() It seems most bluetooth 'audio' modules (ones mounted on a PCB with audio amps, regulators and connectors) just have a bare wore soldered to the antenna, then to the PCB so one can 'connect their own'. are copied without any care about what matching network to use, or the effect of housing, nearby traces etc. Often these are just copied from gerbers of other designs - many inverted F, meander, PCB antennas in general etc. ![]() ![]() As for range, RF is always tricky, and you may have noticed that many cheap modules china kicks out, whilst functional, and sometimes very useful - rarely design good PCB antenna's. Yes, I used that as the VCCIO on my FT232, as well as 220ohm series resistors 'just in case'. Would trust to to supply much, but should be fine for the FT232. ![]() The 1.8V is *usually* broken out on the module on a pin. ![]()
