Thanks everyone for your thoughts on the PCB.
I will take notice of all you have written.
It is clear I need to rework it with some care for
good clearances of tracks.
Working current levels are only about 100mA so I do not need
1mm wide tracks as well. A bit of care might bring the ground, 5V and VBAT (50V)
tracks down to a smaller length but retain 1mm width. All the signal and decoupling
lines could be 0.25mm or something.
When laying out the above board, I found it easy to first route
small parts of the board in a location well separated from the PCB
then move the completed section into place on
the PCB.
This makes the large job a collection of easier to tackle smaller tasks.
Tomorrow is day 2 of my working week. I work 4 days, 2 at work, 2 at home.
PCB routing is a job for a day at work.
