There are 3 multiplexers developed by Vela-Navega: Nmea2Wifi Nmea3Wifi and Nmea4Wifi. You can check here the main differences between the 3 multiplexers or you can visit our forum to get the latest information about new features or updates.

Nmea2Wifi - this multiplexer is built with SMD (Surface Mounting Devices) or TH (Through-Hole) technologies. It can also be supplied as a KIT. All versions are identical in terms of functionality and software. The TH and KIT versions are also identical in terms of hardware. The obvious difference is that the KIT version is assembled by the user.

Exclusive New Nmea4Wifi XL - Price 69€ Starting on September of 2022 we recreated the "old" Nmea4Wifi XL unit. This was very popular as it uses a bigger plastic box (100 x 80 x32 mm instead of 75 x 54 x27 mm) and high quality 1.5mm2 screw terminals. These units are sold exclusively on the Vela Navega website and are fully compatible with the present models. They may be useful in installations where you use thick cables that are difficult to insert with the present "spring" connectors. It uses the new Vela Navega ESP32 development board and its schematic diagram can be found here.

Demo Nmea3Wifi - Add 25€ While the units described here last, you can make a joint purchase of any of the above multiplexers by adding 25 euros to your order. You will receive your multiplexer and one of these units. You need to make 2 Paypal transactions (one by pressing the button for the multiplexer you want and another by pressing the button below). In alternative you may contact me so that I can send a Paypal invoice (or to ask me for my bank account details). Note that the 2 multiplexers need to be sent in the same package.
