In order to make the system reliable and easy to install, I started to design a PCB.
The following circuit board has been realized with the help of EasyEDA software:

### Components
All the components can be ordered from [LCSC](https://www.lcsc.com/) but I had some components in my stuff so I didn't order them all on this site. I put a link for each component to be able to order them.
### PCB printing
I used [JLCPCB](https://jlcpcb.com/)'s printing services to make my printed card because the [EasyEDA](https://easyeda.com/) software came with it.
### Results

### Points of improvement
Of course, we can find different points of improvement concerning the printed circuit, nevertheless, as it is, it is functional. It is therefore a good basis for making adjustments
We can quote for example:
- The lack of a mounting hole to screw the plate
- The gap between the terminals to be screwed could be eliminated and thus reinforce the solidity of the soldered component when screwing a cable tightly
- The DIP switch allowing the choice of the code (of the button of the remote control) to activate the gate could be removed and connected each of the signals to GPIOs of the ESP32 and thus be able to execute different actions depending on the button.
