Let's see what parts I've used first for the prototype and once the new PCB is ready I will share a different part list. The new PCB might use a SMD ESP32 version with on board connector for an external antenna for better range. Then we can see the scheamtic, the PCB and finally the code with a new menu and extra stuff. Check below all parts listed in the update video and some components might be different if you want. Together with the part list you will need the 3D printed case, some wires, screws, etc.
