Here I made some mistakes… I thought I had done the footprints, but after entering the 3D view/rendering of the PCB, I saw that there are only holes in the devices I made (these two in the attached images). I made some area that is seen as non-outline or something like that of the PCB. So I’ll have to fix that 😑

I also made an area on the board that will not have PCB material (FR-4) under the chip/module ESP antenna. This and the 15 mm keepout area around the antenna are to avoid interfering with Wi-Fi and Bluetooth connectivity.
