Going from left to right we have the first Prototype with STM32 Microcontroller. Moving on to a solution without the STM32 and only the ESP32. Prototype 2 does have a battery and works. GPS reception was not the best so we fixed the antenna position in Prototype 3. This prototype is also wraped with a leather cover to make it more "adventurous"
