Hello All,
To start I am a newbie in PCB design and therefore in Kicad software.
My project will basically drive a DC motor and I am not expecting more than 200mA to be running across the traces and also for a short period, due to that and to few components needed on my project I will stick with a 2-layer PCB.
So I was wondering in having both the ground and power plane in the same layer (bottom), this lead me to some questions:
1 - Is there any need at all of having ground and power plane in the same layer (since the current is small), moreover is this a valid design or just something stupid?
2 - I tried to create the two areas in Kicad, the GND plane I managed to create the area and fill it correctly but the Power plane I was only able to create the area, I couldn’t fill it (tried everything: using menu and shortcuts, “B”). Is this an issue or just Kicad saying that there is no reason at all to have two different planes in the same layer?
3 - Is there any recommendation on a PCB book for beginners (PCB not Kicad) ?
Regards,
