Purchasing or Building

You can get a Gnss Sensor Tracker fully assembled from the Wilderness Labs store.	It's also designed so that it can be assembled at home for the adventurous. All design files can be found in the Hardware Design folder.

Getting Started

To simplify the way to use this Meadow-powered reference IoT product, we've created a NuGet package that instantiates and encapsulates the onboard hardware into a GnssTracker class.

1. Add the ProjectLab Nuget package your project:

   • dotnet add package Meadow.GnssTracker, or
   • Meadow.GnssTracker Nuget Package
   • Explore in Fuget.org

2. Instantiate the IGnssTrackerHardware object:

public class MeadowApp : App<F7CoreComputeV2>
{
    IGnssTrackerHardware gnssTracker;

    public override Task Initialize()
    {
        gnssTracker = GnssTracker.Create();
        ...

3. To Access the GNSS Tracker onboard peripherals (Display, for example):

    if (gnssTracker.Display is { } display)
    {
        microGraphics = new MicroGraphics(display);
        microGraphics.Clear();
        microGraphics.DrawText(10, 10, "Hello World");
        microGraphics.Show();
    }
