Are the castellated holes on a breadboard grid? If not I'd try to shrink it horizontally another 1-2mm each side

solar gust
#

cuz i’ve taken measurements with my actual breadboard with a pico as the reference dimensions

#

and i dont have a breadboard template on kicad

#

so i had to rely on actual breadboard

half tundra
solar gust
#

the spacing on the breadboard is 2.54mm

#

i dont use imperial units in indonesia

#

even the breadboard dimensions online doesnt seem to really help

#

im trying to find a breadboard template in which i cant find it

half tundra
solar gust
#

so how should i reference the breadboard dimensions

#

like pico’s 21x51mm

#

many aliexpress breadboards have inconsistent spacing between the halves

#

I had one that was off by almost 50mil

#

one was bought at my local electronics and hobby store in palmerah, jakarta

#

another one was handed out by my teacher in electronic extracurricular in school

#

i’ve never bought anything on aliexpress
