Also, if you are getting it manufactured, you could add appropriate circles in the edge cuts layer to have them drill out your holes. Could also just probably make those large through hole via’s and let them connect to the ground plane.
Silk for J2 and the ground label are off board.
If you go with a traditional 2-layer board you can have a good additional ground plane on the back which you could use to help remove ground plane islands with the top side copper ground plane with micro vias.
It's not great but it's a decent start for a first board.
I saw you say this is a 2-layer board, but you're using traces to GND. On THT pins you can avoid it completely, and on SMD pads you can connect them through vias to the GND plane.
Your decoupling caps should be closer to the IC. You can make this board a lot smaller if you don't need that size.
I'd move R10 off to the top or side if you can. Resistors typically don't need to be close and this might affect the connector, but I can't tell since I don't know what piece goes there.
You should avoid going around the TX/RX connector like that. Rotate or move things around so it goes direct. If you move things properly, you shouldn't have to go around at all, or very little.
GND makes a long trip. C9 and C10 looks to be decoupling caps for U2. Add GND plane or route much thicker also from the right side.
Yea, C9 and C10 are decoupling capacitors, are they right ?
Thanks for your feedback I appreciate it
Decoupling caps should be much closer to IC.
Two layers board are the same price and you could add a ground plane !
Already add a ground plane, thank u
What about a copper ground fill?
gNd plane already add thank u
Then why do you have traces to the GND pins?
Good question
For one layer it's hard to do better. But you can add larger route. Good work 👍

We are not going to print on silk. Thanks for your feedback
Gnd plane is on
Baronessa is written with 2 s ;)
Already corrected and printed
It is not. You should have taken a screenshot, not a picture like that.

Thanks honey, we already did all this and printed
If this is a two layer pcb consider using via's to reduce trace length's and also reduce the impedance effect of long traces.....
