Thank you everyone for all the input you are giving me.
You are all making good points about everything from fuses to reverse polarity protection and the position of the antenna.

The devboard i intend to put on there looks like the picture here.
To me it feels like the antenna is protruding out pretty far from the dev board and will be even further out from my board and the GND plane on the back, i’ve seen worse.

The drawing that looks like the antenna is just to show which way to put the board in the headers.
The keepout rule i made is not needed anymore. I am still learning how to use this programs and i used it as a learning experience when the whole back of the board was used as a GND plane. Which it is not anymore.

I am trying to find out what the peak current might be on the motor in the pump, i have no way of measuring it as i don’t have that fancy multimeter or oscilloscope. I fuse might be usefull i suppose, still need to figure out a peak current.
I found something showing peak current = RMS x 1.414. Which for this motor would be something like 700mA If i have understood it correclt, but i don’t think i have.
RMS is probably not the amps showing on the pump, 350mA.

My learning continues.

No, RMS is not what helps you there. Just a set of different fuses to try out.
It depends on the inertial mass of the whole pump. I’d expect something like 3 times the continuous current.
If the manufacturer supplies the blocking current then you know what you can expect at maximum. But this is easy to measure if you have the motor at hand. It is simply the inner resistance when the motor is at standstill.
