GPS Speedometer on a Nextion display

Speedometer

I wanted to make a speedometer for in my boat. To see the time, speed (kph) and satellites connected. So I made it!

It is a plug and play system. But it take some time before the GPS is connected around 10-15 min. This waiting is way shorter if you use the GPS often. The more satellites are connected the more accurate is the speed.

If you want access to other data like longitude and latitude. You can find it here:
