I was getting ready to start routing, but then I decided to take a quick look at the schematic again and check if the power supply and protection/best practices part of the circuit was all good. I consulted Perplexity and it suggested adding resistors and changing a capacitor on the EN pin of the ESP. I changed it from 100nF to 1uF and added a 10kΩ resistor along with it. I had already added resistors to the SDA and SCL pins and I don’t remember if I changed that..

I also looked up the data for the external components. The display and the battery. I wanted to make a 3D model to make it look better and to get an idea in the EasyEDA rendering. I searched for the display data on the site, on its manufacturer’s website but found nothing. So I googled it and the data came up on a site already known here and there it was fine, that must be it, I needed the thickness in this case ~15mm.

Ah, and I hadn’t noticed that the footprint I made for the display was only for the screen, not the complete module. Then I realized it’s going to be bigger than one of the PCB dimensions I had in mind… It’s supposed to be like that, I hadn’t noticed but in the image I attached with the green arrow it shows that it’s 50x86mm
