Hi,
What is your advice to connect a GPS antenna (see picture) to the NMEA4WIFI ?
I dont want to broke something.
best regards

Hello,
For the data to be read by an input port, say P2, you should connect TX to A2 and GND (the ground wire from the antenna) to B2.

Hi,
The GPS antenna on the picture has 12V power supply. There are several nmea 0183 GPS antennas that require 5V power supply. Is there any 5V output powerful enough for a GPS antenna (max 45mA) available on the Nmea4Wifi?

Hello,
The multiplexer has a 5V switching voltage regulator. It is a red module with a red led light (in older versions this regulator was green and had no led). It has 4 pins. One is EN which is open (in recent versions I just use the other 3 pins leaving that unused). The other 3 pins are Vin Gnd and 5V. Vin is near the unesed EN. The maximum current is 1.3 A but I doubt it would support such a current. The multiplexer takes about 70 mA at 12V. So at 5V it will supply about 186 mA assuming an efficiency of 90% . I assume that it will support the extra 45mA. You need to be careful in getting the 5V out of the regulator (soldering a wire, etc...)
The regulator is this one:
