With the inexpensive cost of electronic components online, I am amassing quite a library of modules and parts to build whatever little contraption my silly little brain dreams up. Lately I've been working on a portable GPS unit using an ESP32, with an off the shelf GPS module and 1" OLED screen.
Quite often I'm in the woods and I know where I am, but I don't know where I want to go. Thus, navigating back home safely is important if I feel like simply walking into the forest alone. I wanted a simple GPS unit where I could calculate distances and display a map of my location, with beacons displaying waypoints and markers.
