PCB design - Question from schematic to PCB | Kicad

Hi all !

I'm coming to you with, probably, a newby question from PCB design.

I'm trying to design my second PCB (the first one had a flaw that I didn't foresaw and was a bust) and I'm coming to you for a small verification.

I'm trying to design a PCB for the following circuit (from https://randomnerdtutorials.com/power-esp32-esp8266-solar-panels-battery-level-monitoring/:

image

I'm going to use a ESP32-CAM .

I already have the kicad project done - the schematics:

and the PCB layout:

image

Now, my question is regarding the wiring from the battery to the two capacitors and then to the ESP32-CAM. Will the wiring, like it is, be the same like in Fritzing design ?

I have this working on a breadboard - but there I wire all the wires on the same rail -

Thank you

    Zones are a bit odd, until you managed to use them once. Maybe create a project with just Vss, Vdd and two resistors in parallel. Then try to play with zones on the PCB design of that simple example. …

    When you add the zone, give it the same net name as the pads that you try to connect.

    Thank you ! I'm not even considering the TP4056 for the PCB - that will be connected to the solar panels. This PCB will only be from output of the TP4056 - it will be connected to the battery holes.…

    Thank you for the replies.

    I will increase the trace width and moved it a bit from the unconnected pads.

    I've changed the layout a bit, so now I have this:

    This way it mimics better all the capacitors being connected to the MCP17000. I'm guessing it's ok.

    Is there any way to test this ? Some kind of simulator ?

    Thank you

    The automated design rule check should tell you if there are problems. The ground traces still look like they are touching the input and output pads  of the regulator.

    I have two cooper layers.  The ground is on one layer and the voltage is on another layer.

    Thank you for the replies !
