a simple way for Recombucks
create a pad
change width, height to 1.3mm; hole diameter to 0.6mm
copy this pad
place 7 of them as shown by recom
group this layout
copy and place as needed
for the connection between the Bucks( V+; V-) set the coppertrace width to 1.2mm. we are running here about 2A.
all other traces can be smaller (0.33 for example)
the solderpads for the leds, etc are also only a coppertrace.
make them big as possible we have to solder the wire here.
1.2mm for the leds will be OK. (0.25mm² wire)
2.5mm for the Powerwires (0.5mm² wire)
minimum length for them 6mm
