There is a reason why I kept the hardware as simple as possible. I'm planning to do a workshop next month with some youngsters where everyone will make there own Sattrack. Most of them have never done something with electronics, so everything needs to be simple as possible.

Instead of using the ESP-01, I bought some WeMos. Those board doesn't cost more, but already have a regulator and usb port on board. Additional I bought a matching prototype pcb where they can add an additional button. This button is for resetting the configuration settings. That way they don't need to reprogram it if they lose the password to acces the settings. My initial thought was to also add a level shifter with a 2N7000 mosfet. But because it's works stable without, I removed that part to make it more simpler. I will leave it optional for the people who wants.

I stilt don't have an idea on how I will make the casing with them. I will probably let them make something out of cardboard and other easy to use materials.
