We can use a GPS active antenna on the FX30.
The bias from FX30 is 3.15VDC.
But what is the maximum curent from the FX30 ?
Unfortunately, this information is not mentioned in FX30 document. Do you concern about power consumption?
Yes, the maximum power consumption from antenna.
I think power consumption depends on your antenna impedance.
Yes, but what is the maximum curent that the FX30 can supply ?
If the antenna power consumption is 50mA, is it OK for the FX30 ?
The maximum bias current for the GNSS port is 300 mA at 3.15 V.
