use ground pours for you pcb
#Esp 32 mini Board
elfin gyro
and I think that sd card is wired wrong
should be like this
still would not hurt to do them on all of the layers
and I would recommend stitching them together
you can always refill the zones by pressing b

idk how it looks on the backside, but I would make sure these ground islands have proper way to the ground plane.
can you send a picture of the backside?
look, the same spots dont have way to the ground from either side, or atleast they have really long ground path. when there is copper pours like this isolated from grounplane, they can act like antennas and amplify interference. You should always strive to keep ground plane unified, without leaving isolated islands
shifts traces around in away that atleast in the backside of the board, there wouldnt be any island and the ground plane would be unified
upperside ground island should be fine aslong as the vias connected to the backside copper pour are in unified ground plane
you have how many layers?
okay, then it is probably fine, I assumed you had only two layer board setup
ground plane in the middle is good, then ground has unified copper pour
yea probably lol

well, no reason not to go with the 4L one
well, you did just post a screenshot of it
yeah, but i just scrolled up and read it
doesn't seem too bad
dim berry
well, no reason not to go with the 4L one
yea and in my understanding even the via inductance is better (smaller) in 4L board versus 2L board, due to the shorter lenght between the layers
dim berry
yea 4L is for sure better
charred beacon
there's just no reason not to except if you're making a big board
i.e. keyboard sized
or making a lot of them
charred beacon
i.e. keyboard sized
and, even then, the cost increase isn't that major
dim berry
and, even then, the cost increase isn't *that* major
yea and routing is easier and board overall peformance is better with 4 layer board

I dont atleast catch any problems with it. I think its most likely fine
